What is a Chip Scale Atomic Clock?

CSAC was a program initiated by DARPA

Goal was to create an atomic clock 100X smaller and 100X less

power consumption than existing technologies

Such a product would be an enabling technology for handheld,

autonomous sensor, and secure comms applications

Symmetricom was a technology leader in the program

from the start

First compliant physics package

First autonomous clock

Symmetricom made the decision

to commercialize CSAC and

accelerate development with its own investment


CSAC Performance =

Breakthrough Benefits

Accuracy and stability to meet the most

demanding applications <<0.1 sec error over a human lifespan

Extremely low power consumption 1/40th or less the power consumption of existing

atomic oscillators.

Tremendous reduction in battery size, cost, and weight.

Extends product deployments

Small size, reduced weight 1/8th the volume, 1/7th the weight of

traditional atomic oscillators.

Enables truly portable applications.


Principles of ANY Atomic Clock

Atomic resonance is intrinsically more stable than quartz local

oscillator.

“Natural” atomic microwave resonance frequency is synthesized

from RF LO.

Control Loop continuously steers LO frequency to atomic

resonance.

RF output (typically 10 MHz) embodies stability of atomic

resonance.

Operates from standard 3.3V Power Supply.

Provides 10 MHz high-impedance square-wave output.


Applications

Applications which benefit

from CSAC

Require precise time for synchronization

without direct connection

Require ability to hold precise time even

in absence of GPS

Need to minimize size, weight, and

power (SWaP)

Examples include:

Portable “man-pack” equipment for

the military

Distributed geophysical sensors,

underground or underwater


Portable Military Applications

Example

Dismounted (Backpack) Jammers

Problem: Need to jam wireless signals used to detonate

Improvised Explosive Devices (IEDs)

First jammers were vehicle-mounted, but ~70%

of all patrols in Afghanistan are on foot.

Dismounted jammers must be synchronized to

allow friendly communications, while blocking

detonation signals.

Solution: CSAC precision enables synchronization, while

its low power consumption reduces the amount

of batteries needed to power the jammer.


Marine Applications

Example

Acoustic pulse hits & penetrates

ocean floor.

Sound travels thru different materials

at different speeds.

Sensors time-stamp when pulse

is received.

Post-processing shows likely places

for oil or natural gas.

Problem: How to keep sensors synchronized in absence of GPS.

How to prolong the time sensors can stay underwater.

Solution: CSAC provides 100x stability improvement compared to current solutions.

CSAC achieves this while consuming 10 to 20% of the power of current solution.
