Low Jitter and Skew DC to 220 MHz Clock Buffer
Key Features
DC to 220 MHz operating frequency range Low output clock skew: 70ps-typ Low part-to-part output skew: 100 ps-typ 3.3V to 2.5V operation supply voltage range Low power dissipation: - 9 mA-typ at 33MHz - 11 mA-typ at 66MHz - 15 mA-typ at 166MHz One input to nine (9) output fanout buffer drivers Available in 16-pin SOIC package Available in Commercial and Industrial grades Available in Lead (Pb) free package
Description
The SL23EP09NZ is a low skew, jitter and power fanout buffer designed to produce up to nine (9) clock outputs from one (1) reference input clock, for high speed clock distribution. The SL23EP09NZ products operate from DC to 140MHz. Refer to SL2309NZ product for DC to 140MHz-max frequency range. Also refer to SL2304NZ or SL23EP04NZ products for 1:4 clock fanout buffers from 2.5V to 3.3V power supply and DC to 220MHZ frequency range.
Benefits
Up to nine (9) distribution of input clock Low skew Low Jitter Low power dissipation
Applications
General Purpose PCI/PCI-X Clock Buffer Printers, MFPs and Digital Copiers PCs and Work Stations Routers, Switchers and Servers Datacom and Telecom High-Speed Digital Embeded Systems

SL23EP09NZ
General Description
The SL23EP09NZ is a low skew, jitter and power fanout buffer designed to produce up to nine (9) clock outputs from one (1) reference input clock, for high speed clock distribution, including PCI/PCI-X applications.
Output Clock Skew
All outputs should drive the similar load to achieve outputto-output skew specifications as given in the switching electrical tables.
Input and output Frequency Range
The input and output frequency is the same (1x) for SL2309NZ and the product operates from DC to 220MHz clock range with 15pF and 100MHz with 30pF output loads.
Power Supply Range (VDD)
The SL23EP09NZ is designed to operate from 3.3V to 2.5V VDD power supply range. An internal on-chip voltage regulator is used to provide to constant power supply of 1.8V, leading to a consistent and stable electrical performance in terms of skew and jitter. The SL23EP09NZ I/O is powered by using VDD. Refer to SL2309NZ product for DC to 140MHz-max frequency range. Contact SLI for 1.8V power supply Buffers and ZDB products.
High Drive Capability
The SL23EP09NZ is designed to meet high drive requirements for up to 30pF load condition per electrical specifications. If lower drive levels are required refer to SL2309NZ fanout buffer product.

External Components & Design Considerations
Typical Application Schematic
Comments and Recommendations
Decoupling Capacitor: A decoupling capacitor of 0.1 F must be used between all VDD and VSS pins. Place the capacitor on the component side of the PCB as close to the VDD pin as possible. The PCB trace to the VDD pin and to the GND via should be kept as short as possible. Do not use vias between the decoupling capacitor and the VDD pin. Series Termination Resistor: A series termination resistor is recommended if the distance between the output clocks and the load is over 1 1/2 inch. Place the series termination resistors as close to the clock outputs as possible.
