Application Specific Crystals, Oscillators, TCXOs, VCXOs and OCXOs

Cost-Effective Development with Rapid Turnaround

Engineered Solutions from Minor Modifications to Full Custom

Dedicated Engineering Support Team for Your Application

Advanced Frequency Control Expertise from the World Leader

At Fox, we pride ourselves on offering the world's broadest range of standard, stocked, off-the-shelf crystals and oscillators. We also prideourselves on knowing what the market needs. And we understand that, more and more, yourapplications may require a frequency control devicewith characteristics or capabilities that are not metby our standard offerings. That's why we'vedeveloped the Fox Customer Technology Center(CTC)…as a resource for your special needs. Our new CTC is designed specifically to delivercost-effective, fast-turn solutions to highlyapplication-specific requirements for crystals,oscillators, TCXOs, VCXOs and OCXOs.

From tweaks to full customYour custom frequency control need may be for a slight modification to anexisting product…a significant variation of a current product…or an entirely new concept never before offered, butjust what you need for your unique application.Whatever it takes, the FOX CTC is prepared totackle it. We'll evaluate your need and provide a candid response on what it will take to meet that need. And, if we simply can't do it, we'll

tell you that, too…and perhaps suggest another solution to the problem. Our applicationengineers are skilled at creating just the rightsolutions. If your application warrants it, we'll send a FOX FAE to your site to discuss thesituation with you in person.

The Fox CTC has already proven to be atremendous success: several innovative productshave already been developed by the CTC, including a 77 MHz TCXO, which was designed,developed, produced, tested and shipped in amatter of days…rather than the four monthsquoted by our competitors!!

Engineered solutions for your applicationAt the heart of the Fox CTC is a powerful, focusedengineering capability, representing an integrationand expansion of our design engineering andcustomer support resources, and a significantlyexpanded Field Application Engineering staff. The CTC specializes in the development of TCXOs,VCXOs and OCXOs over a wide range offrequencies and output structures not previouslyaddressed. The CTC also employs patented

technology for oscillator and RF applications up to1.4 GHz, opening up new possibilities for highly engineered telecom and fiber optic products.

The CTC is supported by a newly formed Design Central, comprising the Fox's DEN (DesignEngineering Network) and the Fox CustomerApplication Team (CAT). The latter is a dedicated,multi-discipline team consisting of the primarycustomer service person, technical supervisor,design engineer and marketing person serving that particular customer. On the production side,the CTC has extensive manufacturing tools at itsdisposal, including an expanded range of thick and thin film, laser, pick and place, wire bondingand wafer handling processes.

Our CTC is your resource!No matter how unique your frequency control needmay be, chances are high that it can be met at theFox Customer Technology Center. Call us with your problem…or visit our CTC website atfoxonline.com/ctc…and we'll provide the solution!

DISTRIBUTOR BRIEFINGThe Fox Distribution Program includes all of the Fox Part Numbers identified as DISTRIBUTOR STOCKINGSTANDARDS plus all of our JITO-2 product line. Fox franchised distributors maintain inventory of theSTANDARDS to assure a constant supply to customers who design these items into their products. Of course,JITO-2 products are not maintained in inventory as they are 'built to order and schedule' for JIT delivery.

This STANDARDS PROGRAM is formalized in our distributor relationship and in our Contract Manufacturingrelationships, providing maximum global flexibility to our OEM customers. Design engineers can be confidentthat a STANDARD oscillator or crystal will be available for future manufacturing needs. A check with the Foxwebsite will reveal current address and phone number information for all of the authorized distributors in yourarea. The feature "StockCheck" on Fox's home page (www.foxonline.com) may be used to confirmdistributor inventory. Fox global distributors may have regional marketing centers in certain areas of the world,easily located through the distributors' website.

RFXO Description: The RFXO family of Oscillators is an ASIC-driven crystal-based line of frequency control products. These RFXOs are available as standard Crystal Oscillators (XOs) or Voltage Controlled Crystal Oscillators (VCXOs) with frequencies from 600MHz to 1.25GHz. The RFXO family of products generates an output at the frequency of operation (fo) with low jitter and phase noise in the frequency domain. Low clock jitter is essential to achieve a low bit error rate in optical data communications and also allows for full use of the allotted bandwidth. This makes the RFXO ideally suited for the next generation of low jitter clocks and data streams for SONET/SDH applications.

Fox filters offer excellent features such as sharp cut off characteristics,low loss and high stability over a wide temperature range which aresuperior to LC Filters and Ceramic Filters.

The basic building block for all custom built Fox filters is the two-pole monolithic filter available in standard package as shown. Two-pole monolithic filters are cascaded to produce four, six and eightpole filter responses with the addition of coupling capacitorsbetween two-pole sections. Standard Fox filters are available withcenter frequencies from 10.7 MHz to 90 MHz, and from two toeight poles.

For custom made filters, please specify the following: Holder Size Nominal Frequency Pass Bandwidth

Note: 45F Series 45.000 MHz fundamental is a special filter designed for mobileradio and cellular phone applications.

Figure 3

Of the various elements, the "AT" cut has become themost popular as it is available at relatively high frequencies,exhibits excellent frequency vs temperature stability andis widely available at reasonable cost. The frequency vs.temperature capabilities of the "AT" cut crystal unit areillustrated in Figure 4.

Figure 4

Fundamental vs. OvertoneThis is of concern primarily when specifying the "AT"cut crystal unit. These units increase in frequency as thethickness of the resonator plate is diminished. At somepoint, typically around 30MHz, the plate becomes toothin for efficient processing. As the "AT" will resonate atodd integer multiples of the fundamental frequency, it isnecessary to specify the desired order of overtone whenordering higher frequency crystals.

Drive LevelDrive level is the amount of power dissipated by thecrystal. Drive level is usually specified in terms of microor milliwatts, with a typical value being 100 microwatts.

Quartz crystal units serve as the controlling element ofoscillator circuits by conversion of mechanical vibrationsto electrical current at a specific frequency. This isaccomplished by means of the "Piezoelectric" effect.Piezoelectricity is electricity created by pressure. In apiezoelectric material, the application of mechanicalpressure along an axis will result in the creation of anelectrical charge along an axis at right angles to the first.In some materials, the obverse piezoelectric effect is found,which means that the imposition of an electric field onthe ends of an axis will result in a mechanical deflectionalong an axis at right angles to the first. Quartz is uniquelysuited, in terms of mechanical, electrical and chemicalproperties, for the manufacture of frequency controldevices. Quartz crystal units which oscillate within certainfrequency and temperature ranges have been developedover the years. Figure 1 shows the location of specificelements within a quartz stone.Figure 1

The elements as shown above vibrate in various modes,the most important of which are the extensional, flexuraland shear. The mode of vibration determines themaximum frequency, stability vs. temperature, andresistance of a given element. The various modes ofvibration are shown in Figure 2, while a comparison ofthe various frequency stabilities vs temperature are shownin Figure 3.Figure 2

Series vs. Parallel"Series" resonant crystals are intended for use in circuitswhich contain no reactive components in the oscillatorfeedback loop. "Parallel" resonant crystals are intendedfor use in circuits which contain reactive components(usually capacitors) in the oscillator feedback loop. Suchcircuits depend on the combination of the reactivecomponents and the crystal to accomplish the phase shiftnecessary to start and maintain oscillation at the specifiedfrequency. Basic depictions of two such circuits areshown below.Figure 5

Load CapacitanceThis refers to capacitance external to the crystal, containedwithin the feedback loop of the oscillator circuit. If theapplication requires a "parallel" resonant crystal, the valueof load capacitance must be specified. If the applicationrequires a "series" resonant crystal, load capacitance isnot a factor and need not be specified. Load capacitanceis the amount of capacitance measured or computedacross the crystal terminals on the PCB.

Frequency ToleranceFrequency tolerance refers to the allowable deviation fromnominal, in parts per million (PPM), at a specifictemperature, usually +25°C.

Frequency StabilityFrequency stability refers to the allowable deviation, inparts per million (PPM), over a specified temperaturerange. Deviation is referenced to the measured frequencyat +25°C.

AgingAging refers to the cumulative change in frequencyexperienced by a crystal unit over time. Factors affectingaging are excessive drive level, various thermal effects,wire fatigue and frictional wear. Circuit designincorporating low operating ambients and minimum drivelevel will reduce the aging rate.

PullabilityPullability refers to the change in frequency of a crystalunit, either from the natural resonant frequency (Fr) to aload resonant frequency (FL), or from one load resonantfrequency to another. See Figure 6. The amount ofpullability exhibited by a given crystal unit at a given valueof load capacitance is a function of the shunt capacitance(Co) and the motional capacitance (C1) of the crystalunit.Figure 6

Equivalent CircuitThe equivalent circuit, shown in Figure 7, is an electricaldepiction of the quartz crystal unit when operating at afrequency of natural resonance. The Co, or shuntcapacitance, represents the capacitance of the crystalelectrodes plus the capacitance of the holder and leads.R1, C1, and L1 compose the "motional arm" of the crystaland are referred to as the motional parameters. Themotional inductance (L1), represents the vibrating massof the crystal unit. The motional capacitance (C1),represents the elasticity of the quartz and the resistance(R1), represents bulk losses occurring within the quartz.

Figure 7

Impedance/Reactance CurveA crystal has two frequencies of zero phase, as illustratedin Figure 8. The first, or lower of the two, is the SeriesResonant Frequency, denoted as (fs). At this point, thecrystal appears resistive in the circuit, impedance is at aminimum and current flow is maximum. As the frequencyis increased beyond the point of series resonance, thecrystal appears inductive in the circuit. When thereactances of the motional inductance and shuntcapacitance cancel, the crystal is at the Frequency ofAnti-resonance, denoted as (fa). At this point, impedanceis maximized and current flow is minimized.

Figure 8

Quality Factor (Q)The "Q" value of a crystal unit is a measure of the unitsrelative quality, or efficiency of oscillation. The maximumattainable stability of a crystal unit is dependent on the"Q" value. In Figure 8 above, the separation betweenthe series and parallel frequencies is called the bandwidth.The smaller the bandwidth, the higher the "Q" value, andthe steeper the slope of the reactance. Changes in thereactance of external circuit components have less effect(less "pullability") on a high "Q" crystal, therefore such apart is more stable.

Calculation of Load CapacitanceIf the circuit configuration is as shown in Figure 5 for theparallel version, the load capacitance may be calculatedby means of the following equation:

Cstray includes the pin to pin input and output capacitanceof the microprocessor chip at the Crystal 1 and Crystal 2pins, plus any parasitic capacitances. As a rule of thumb,Cstray may be assumed to equal 5.0 pF. Therefore, ifCL1 = CL2 = 50pF, CL = 30pF.

Trim SensitivityTrim sensitivity is a measure of the incremental fractionalfrequency change for an incremental change in the valueof the load capacitance. Trim sensitivity (S) is expressedin terms of PPM/pF and is calculated by the followingequation:

Where (Ct) is the sum of Co and CL.

DESIGN NOTESTECHNICAL


Crystal controlled oscillators may be considered as consistingof an amplifier and a feedback network that selects a part ofthe amplifier output and returns it to the amplifier input. Ageneralized depiction of such a circuit is shown below.

Figure 1.0

In order for an oscillator circuit to operate, two (2)conditions must be met:

(A) The loop power gain must be equal to unity.(B) The loop phase shift must be equal to 0, 2Pi, 4Pi, etc. radians.

The power fed back to the input of the amplifier must beadequate to supply the oscillator output, the amplifier input,and to overcome circuit losses.

The exact frequency at which an oscillator will operate isdependent on the loop phase angle shifts within the oscillatorcircuit. Any net change in phase angle will result in a changein the output frequency. As the usual goal of an oscillator isto provide a frequency that is essentially independent ofvariables, some means of minimizing the net phase shift mustbe employed. Perhaps the best, and certainly the mostcommon means of minimizing the net phase shift is to use aquartz crystal unit in the feedback loop.

The impedance of a quartz crystal changes so dramaticallywith changes in the applied frequency that all other circuitcomponents can be considered as being of essentiallyconstant reactance. Therefore, when a crystal unit is used inthe feedback loop of an oscillator, the frequency of the crystalunit will adjust itself so that the crystal unit presents areactance which satisfies the loop phase requirements.A depiction of the reactance vs. frequency of a quartz crystalunit is shown below.

Figure 2.0

As is apparent from Figure 2.0, a quartz crystal unit has twofrequencies of zero phase. The first, or lower of the two, isthe series resonant frequency, usually abbreviated as Fs. Thesecond, or higher of the two frequencies of zero phase is theparallel, or anti-resonant frequency, usually abbreviated asFa. Both the series and parallel resonant frequencies appearresistive in an oscillator circuit. At the series resonant point,the resistance is minimal and the current flow is maximal.

At the parallel point, the resistance is maximal and the currentflow is minimal. Therefore, the parallel resonant frequency,Fa, should never be used as the controlling frequency of anoscillator circuit.

A quartz crystal unit can be made to oscillate at any pointalong the line between the series and parallel resonant pointsby the inclusion of reactive components (usually capacitors)in the feedback loop of the oscillator circuit. In such a case,the frequency of oscillation will be higher than the seriesresonant frequency but lower than the parallel resonantfrequency. Because of the fact that the frequency resultingfrom the addition of capacitance is higher than the seriesresonant frequency, it is usually called the parallel frequency,though it is lower than the true parallel frequency.

Just as there are two frequencies of zero phase associatedwith a quartz crystal unit, there are two primary oscillatorcircuits. These circuits are generally described by the typeof crystal unit to be used, namely series or parallel.

SERIES CIRCUIT:A series resonant oscillator circuit uses a crystal which isdesigned to operate at its natural series resonant frequency.In such a circuit, there will be no capacitors in the feedbackloop. Series resonant oscillator circuits are used primarilybecause of their minimal component count. These circuitsmay, however, provide feedback paths other than through thecrystal unit. Therefore, in the event of crystal failure, such acircuit may continue to oscillate at some arbitrary frequency.A depiction of a basic series resonant oscillator circuit isgiven below.

Figure 3.0

As is apparent from Figure 3.0, a series resonant oscillatorcircuit provides no means of adjusting the output frequency,should adjustment be required. In the above circuit, resistorR1 is used to bias the inverter and to cause it to operate in itslinear region. This resistor also provides negative feedbackto the inverter. Capacitor C1 is a coupling capacitor, usedto block DC voltage. Resistor R2 is used to bias the crystalunit. This resistor strongly influences the drive current seenby the crystal unit, therefore care must be taken that too smalla value is not chosen. Crystal unit Y1 is a series resonantcrystal unit, specified to operate at the desired frequencyand with the desired frequency tolerance and stability.

PARALLEL CIRCUIT:A parallel resonant oscillator circuit uses a crystal unit whichis designed to operate with a specified value of loadcapacitance. This will result in a crystal frequency which ishigher than the series resonant frequency but lower than thetrue parallel resonant frequency. These circuits do not providepaths other than through the crystal unit to complete thefeedback loop. In the event of crystal unit failure, the circuitwill not continue to oscillate. A basic depiction of a parallelresonant circuit is given below.

Figure 4.0

This circuit uses a single inverter, with two capacitors in thefeedback loop. These capacitors comprise the loadcapacitance and together with the crystal unit, establish thefrequency at which the oscillator will operate. As the valueof the load capacitance is changed, so is the output frequencyof the oscillator. Therefore, this circuit does provide aconvenient means of adjusting the output frequency, shouldadjustment be required.The resistors R1 and R2 serve the same functions as detailedfor the series resonant circuit shown in Figure 3.0. The twoload capacitors, CL1 and CL2, serve to establish the frequencyat which the crystal unit and therefore the oscillator willoperate. Crystal unit Y1 is a parallel resonant crystal unit,specified to operate with a specified value of loadcapacitance, at the desired frequency and with the desiredfrequency tolerance and stability.

LOAD CAPACITANCE:Reference has been made to a specified value of loadcapacitance. Load capacitance may be defined as that valueof capacitance, either measured or calculated, present in theoscillator circuit, across the connection points of the crystal.In the case of a series resonant circuit, there is no capacitancepresent between the connecting points of the crystal unit andtherefore, load capacitance need not be specified for a seriesresonant crystal unit. In the case of a parallel resonantoscillator circuit, capacitance is present. As a directmeasurement of this capacitance is impractical, it is usuallynecessary to calculate the value. The calculation of the valueof the load capacitance is done with the following equation:

CL = + CS (1)

Where CL1 and CL2 are the load capacitors and CS is thecircuit stray capacitance, usually 3.0 to 5.0 pF.

It must be noted that changes in the value of the loadcapacitance will result in changes in the output frequency ofthe oscillator. Therefore, if precise frequency control isrequired, then a precise specification of load capacitance isrequired. To illustrate, assume that a crystal unit is specifiedto operate at a frequency of 20.000 MHz with a loadcapacitance of 20.0 pF. Assume that the crystal unit is thenplaced in a circuit which presents a value of 30.0 pF. Thefrequency of the crystal unit will then be lower than thespecified value. Conversely, should the circuit in questionpresent a value of 10.0 pF, the frequency will be higher thanthe specified value. The relationship between frequency andload capacitance is shown below.

Figure 5.0

DRIVE LEVEL:The drive level is the power dissipated by the crystal unitwhile operating. The power is a function of the appliedcurrent, and is usually expressed in terms of Milliwatts orMicrowatts. Crystal units are specified as having certainmaximum values of drive level, which change as functions ofthe frequency and mode of operation. It is well to consultwith the crystal unit vendor as to the maximum value of drivelevel allowed for a particular crystal unit. Exceeding themaximum drive level for a given crystal unit may result inunstable operation, increased aging rates, and in some cases,catastrophic damage. The drive level may be calculated bythe following equation:

POWER = (Irms2 * R) (2)

Where I is the rms current through the crystal unit and R isthe maximum resistance value of the specific crystal unit inquestion. Equation (2) is simply Ohms law for power.

Measurement of the actual drive level in an operatingoscillator circuit may be accomplished by temporarilyinserting a resistor in series with the crystal unit. The resistormust be of the same ohmic value as the crystal unit. Thevoltage drop across the resistor may then be read and thecurrent and power dissipation calculated. The resistor mustthen be removed. As an alternative means of measuring thedrive level, a current probe may be used at the output lead ofthe crystal unit, if space permits.

THEORY OF OPERATIONTECHNICAL


FREQUENCY VS OVERTONE MODE:The frequency of a quartz crystal unit is limited by the physicaldimensions of the vibrating quartz element. In some cases,the limiting dimension(s) are the length and width. In the caseof the most popular crystal unit, the AT cut crystal unit, thelimiting dimension is the thickness of the vibrating quartzelement. As the thickness is diminished, the frequency isincreased. At some point, usually around 30.000 MHz, thethickness of the quartz plate becomes too thin for processing.

Should it be desired to develop an oscillator at a frequencyhigher than the limiting frequency, advantage must be takenof the fact that quartz crystal units will oscillate at odd integermultiples of their fundamental frequency. We may definethe fundamental frequency as that frequency whichnaturally occurs at a given set of mechanical dimensions.Therefore, if a crystal unit has a fundamental frequency of10.0 MHz, it can also be made to oscillate at 3, 5, 7, etc.times the fundamental. That is, the unit will oscillate at 30.0,50.0, 70.0, etc. MHz. These multiples of the fundamentalfrequency are called overtones and are identified by theinteger of multiplication, as in the third overtone, the fifthovertone, etc. When use at an overtone frequency isrequired, the crystal unit must be specified to operate at thedesired frequency and on the desired overtone. One shouldnever attempt to order a fundamental mode crystal unit andthen operate it at an overtone frequency. This is so due to thefact that the crystal manufacturing processes differ forfundamental and overtone crystal units.

In many cases, the characteristics of the integrated circuitused in a particular oscillator design dictate that thefundamental frequency of the crystal unit be suppressed inorder to ensure operation at the desired frequency and onthe desired overtone. In such cases, it is usually necessary tomodify the oscillator circuit. One method of modificationis to add a tank circuit, consisting of an inductor and acapacitor. These modifications are shown in Figure 6.0 and7.0

Figure 6.0

Figure 6.0 depicts the modification of a series resonantcircuit while Figure 7.0 depicts the modification of a parallelresonant circuit.

Figure 7.0

In both cases, the tank circuit is tuned to resonate at somefrequency between the fundamental and the desiredfrequency. This results in the unwanted frequency beingshunted to ground, leaving only the desired frequency beingpresent at the output of the oscillator.

DESIGN CONSIDERATIONS:For good operation of an oscillator circuit, certain designconsiderations should be followed. In all cases, it isrecommended that parallel traces be avoided in order toreduce circuit stray capacitance. All traces should be kept asshort as possible and components should be isolated in orderto prevent coupling. Ground planes should be used to isolatesignals.

NEGATIVE RESISTANCE:For optimum performance, an oscillator circuit must bedesigned in such a way as to enhance negative resistance,which is sometimes called the oscillation allowance.Evaluation of the amount of negative resistance in a givencircuit is accomplished by temporarily installing a variableresistor in series with the crystal unit. The resistor should beset initially at its lowest setting, preferably close to zeroohms. The oscillator is then started and the output monitoredon an oscilloscope. The variable resistor is then adjusted sothat resistance is increased while the output is continuouslymonitored. At some value of resistance, oscillation will bestopped. At this point, the variable resistor is measured todetermine the ohmic value at which oscillation ceased. Tothis value, the maximum resistance of the crystal unit, asspecified by the vendor, must be added. The total ohmicresistance is deemed to be the negative resistance or theoscillation allowance. For good, reliable circuit operation,it is recommended that the negative resistance be a minimumof five times the specified maximum resistance value of thecrystal unit.

Values of negative resistance exceeding five times the maxi-mum resistance of the crystal unit are better yet. As negativeresistance tends to decrease at elevated temperatures, it isrecommended that the test be performed at the highest tem-perature of the operating range.

FREQUENTLY ASKED QUESTIONS

TECHNICAL INFOWhat is the difference between series resonant and parallelresonant crystals?

All quartz crystal resonators have a series resonantfrequency (fs, frequency of lowest impedance). At thisfrequency, the crystal appears resistive in the circuit.Crystals can be pulled from this series frequency byadding reactance (capacitance) in series with the crystal.When operated in combination with an external loadcapacitance (CL) the crystal oscillates in a frequency rangeslightly above its series resonant frequency. This is theparallel (load resonant) frequency.

When ordering a parallel crystal, always specify thenominal parallel resonant frequency and the amount of loadcapacitance in picofarads (pF). Alternatively, a standardvalue of CL (such as 20pF) can be ordered; the capacitorvalues are then calculated to match the crystal CL. Notethat a series type will oscillate in a parallel oscillator, andvice versa. The observable difference is a frequency offsetof less than + 1000 PPM (0.1%) from the nominalfrequency.

The load capacitance (CL) of my parallel resonantcrystal is rated at 20pF. How do I calculate the value ofthe load capacitors used in my parallel resonantoscillator circuit?

Use this formula to approximate the value of capacitorsneeded:

CL=((C1 x C2) / (C1 + C2)) + Cstray

Cstray is the stray capacitance in the circuit, typically 2-5pF. If the oscillation frequency is high, the capacitorvalues should be increased to lower the frequency. If thefrequency is low, the capacitor values should be decreased,thus raising the oscillation frequency. It is desirable tokeep C1 and C2 of equal value for optimum symmetry.When CL=20pF, C1 and C2 will be approximately 27-33pFeach, depending on the amount of stray capacitance.

Can I get crystals rated for 40° C to +85° C?

Yes, this industrial temperature range (40° C to +85° C)is optional on most crystals. Depending on the crystalpackage, temperature ranges of up to -55° C to +105° Cmay be available. Contact Foxs engineering departmentto discuss your specific requirements.

What happens if I operate a crystal outside of its specifiedtemp range?

We do not recommend that you operate a crystal outsideof its specified temp range. The most notable change willbe a greater frequency drift due to the increasedtemperature extremes. Another and more serious problemthat can occur is activity dips. Activity dips can cause theoscillator to stop oscillating at a specific temperature.

What happens if I operate a crystal over its maximumdrive level spec?

Exceeding the maximum drive level (power dissipation)of a crystal can lead to an increased rate of aging, DriveLevel Dependency (DLD) problems, increased intensityof activity dips that can stop oscillation and, at very highdrive levels, breakage of the crystal blank.

What is an activity dip?

An activity dip is defined as an abrupt increase in EffectiveSeries Resistance (ESR) with an associated shift inresonant frequency over a narrow range of a few degreesCelsius. Activity dips can cause an oscillator to stoposcillating at a specific temperature, then restart as thetemperature continues to change. This is because theoscillator has insufficient loop gain to maintainoscillation. The amount and intensity of activity dips areproportional to the drive level. As the drive level increases,so does the intensity of the activity dips.

I have an existing design that uses a HC49U. Whatshould I consider if I change to the smaller HC49Scrystal, or an SMD crystal?

Drive Level HC49U crystals are typically rated 1.0mWmax, while the HC49S and most SMD crystals are rated atonly 0.5mW or 0.1mW maximum. See question 5 for moreinformation on exceeding the maximum drive level of acrystal.Pullability some applications require tuning thefrequency of the oscillator, either by mechanically orelectrically changing the value of load capacitance. TheHC49S and surface mount crystals have less pullabilitythan the HC49U. It is important to verify whether theHC49S or the surface mount crystal will have sufficientpull range for the application.ESR The Equivalent Series Resistance (ESR) is generallyhigher with the HC49S and surface mount crystals, andcan cause a problem if the oscillator circuit does not havesufficient loop gain.

Should I focus my design on a series or parallel crystal?

Why dont HC49S and surface mount crystals pull asmuch as HC49U crystals?

The HC49U crystal utilizes a circular AT-cut crystal blank.Due to their small size, most surface mount crystals use arectangular AT-strip cut crystal blank. (Strip refers tothe rectangular shape of the blank.) While both are AT-cutblanks, several differences exist due to their differentgeometries. In general, given the same frequency andovertone, an AT-strip cut will have a lower ShuntCapacitance (CO) and Motional Capacitance (C1) than theAT-cut. Because pullability is a function of the capacitanceratio CO/C1, AT-strip crystals have less pullability.

What is the difference between AT- and BT-cuts?

Both AT and BT indicate singularly rotated Y-axis cutsthrough the quartz crystal. The BT is cut at an angleapproximately opposite that of the AT.

BT-cut blanks are thicker than AT-cuts at the samefrequency; therefore, higher fundamental modefrequencies are possible with the BT before the blankbecomes too thin to process. BT-cuts have a parabolicfrequency vs. temperature response while AT-cuts have acubic response. Thus, over a given temperature range, theBT will exhibit a greater frequency shift than the AT. Inaddition, BT-cuts tend to have a lower capacitance ratio(CO/C1) and, as a result, less pullability.

What are the differences between AT-cuts and AT-stripcuts?

The differences are in size, shape and some performancecharacteristics. AT-cut crystal blanks are circular, and AT-strip cut crystal blanks are rectangular. Both types are AT-cuts, but several differences in performancecharacteristics exist because of the different geometriesof the blanks. In general, given the same frequency andovertone, the AT-strip will have a lower value of ShuntCapacitance (CO) and Motional Capacitance (C1). It willalso have a higher value of Effective Series Resistance(ESR) and Motional Inductance (L1). Because pullabilityis a function of CO and C1, AT-strip cut crystals have lesspullability than circular AT-cut crystals.
