SL23EP09NZ
General Description
Output Clock Skew
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.
All outputs should drive the similar load to achieve output-
to-output skew specifications as given in the switching
electrical tables.
Power Supply Range (VDD)
Input and output Frequency Range
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.
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.
High Drive Capability
Refer to SL2309NZ product for DC to 140MHz-max
frequency range.
The SL23EP09NZ is designed to meet high drive
requirements for up to 30pF load condition per electrical
specifications.
Contact SLI for 1.8V power supply Buffers and ZDB
products.
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 0.1ȝF 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 ½ inch. Place the series termination resistors as close to the clock outputs as possible.
