Why ON is Re-launching the Zero Delay Buffers?

• ON made a backend processing change requiring a PCN to be issued.

• Standardizing all products in industrial temp only and lead free only.

• A design change was made to correct an application issue

3

• All OPNs made active by Feb. 2008• Consolidated all commercial temperature range OPNs into industrial temperature

range OPNs. All NB230xA OPNs are designated with an "I" for industrial temp range. The ZDB datasheets are updated to say that the NB230xA ZDBs are guaranteed to operate across commercial AND industrial temperature ranges.

NOTIFICATION• Change Title: Final Notification for ON Semiconductor Zero Delay Buffer Backend

Processing• Issue Date: 2008-01-08• Affected Product Family Description: This is the FPCN to IPCN 15741 available at

www.onsemi.com ON Semiconductor will be manufacturing backend assembly and test process for the Zero Delay Buffer products. Electrical datasheet parameters and specifications will not change. This qualification will allow ON Semiconductor to meet the increasing demand for these types of devices. During the qualification, a design fix was implemented to prevent a potential problem with customer applications operating between a 15 and 30 MHz frequency range. Product with a date code of 0743 or later represents the design tweak. Prior inventory was purged. The backend processing will be performed at the ON Semiconductor OSPI facility in Carmona Philippines. Key Items Affected by Change: Backend Packaging Process

• A device that fans out one clock signal and drives multiple clocks signals• Built with a PLL (see diagram)• Accepts one External Reference Clock Input and a Feedback Input• Feedback Input pin is typically driven by one of the Outputs• PLL synchronizes the REF input with the Feedback input while maintaining

effectively “zero” delay between the REF input and the outputs (Feedback)• The phase detector adjusts the output frequency of the VCO so that its two

inputs have no phase or frequency difference • Provides an output synchronous to the Reference input• Maintains minimal output-to-output skew PLL

Zero Delay Buffer (ZDB) - Description

7

• High Performance : 133MHz• Low skew : 250ps max output-to-output skews• Fast output edge rate : ≤1.5ns • REF to CLKOUT Propagation Delay : 0ps typ., +/-350ps max• Operating Temperature Ranges: Industrial (-40º C to +85º C)• Voltage supply: 3.3V power supply• Packaged in 16-pin SOIC and TSSOP (2308/09); or 8-pin SOIC (2304) and TSSOP

(2304/05) Pb-free• By connecting the CLKOUT output to the feedback FBK input (2304/08), the

propagation delay from the REF input to any clock output will be nearly zero.• A big advantage of the NB230xA is that they allow the system designer to adjust or

move the output clocks forward or backward in time with respect to the reference clock, to fine-tune a design.

• The PLL buffer needs a reference clock from the main system. It then generates 4 or 8 clock signals with zero delay compared to the reference clock. The system only needs to provide one clock signal, which greatly reduces the number of clock signals generated (minimize EMI).

Key Features

Zero-Delay Buffers Solve Clock Problems

ON Semiconductor’s line of Zero-Delay Buffers eliminate clock-propagation delays and allow clock distribution with up to 9 outputs. ZDB’s also allow the designer to compensate for propagation delays and output-to-output skew mismatches that are caused by variations in trace length and capacitive loading on printed-circuit-board interconnects.

Markets and End Equipment

• Memory Array• Storage Area Networks• Network Attached Storage• Servers / Workstations• Networking / Telecom• Routers, Gateways, Switches• Base Stations• Line Cards• Set Top Box• DVR / Digital TV

9

• Clock distribution applications.• High-speed motherboard applications, including those using 133-MHz SDRAM• Memory clock module trees where parallel SDRAMs require idnetical clocks. They

also function in applications requiring multiple low-skew clocks that are phase-matched to a reference clock.

• DIMM or PCI bus clocking• High performance Phase-Lock Loop Clock Distribution for 100/133 MHz Registered

DIMM Synchronous DRAM modules for server/workstation/PC applications• Networking applications such as Switched Ethernet, PLL drivers are used to de-skew

the delay through large clock buffers. • Applications where the system designer needs large multiple clock signals that are in

complete sync with a reference clock. • Used to de-skew the delay through large clock trees. • Significantly large memory arrays need this clocking scheme.

Q&A

• Why are we re-introducing these devices?– Due to a backend processing location addition.

• Is there any difference between the original product and the new released product datasheet electrical specifications?

– No, there is no difference. Datasheets have been updated with the new ordering nomenclature.

• Will there be a nomenclature change?– Yes, commercial grade temp is being replaced by the industrial temp grade part

number and all leaded product is being offered in lead free only. • Will this require my customer to requalify?

– Many customers may choose to re-qual due to a backend change. In many instances it will be a paper qual only. All electrical parameters have been matched.

• Why was a design change made?– Some applications with input frequency between 25-30 MHz range experienced

output instability issues.

13

Q&A continued

• When will samples be available?– We are accepting sample orders now.

• How can I get a sample?– Samples are to be entered into ProChannel.

• When will the product be released into production?– All products are released into production.**

• What is the current lead-time for the production product? – Current lead time is 4 weeks.

• How do I know my customer will get the redesigned product?– The design change was implemented on product with a date code of 0743 or

after. All prior inventory was purged. • Where do I go to get competitor cross references?

– Supplied soft copy of cross reference or to the onsemi.com home page utilizing the cross reference tool.
