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 output-
to-output skew specifications as given in the switching
electrical tables.

The input and output frequency is the same (1x) for
SL2309NZ and the product operates from DC to
220MHz clock range with 15pF and 134MHz with 30pF
output loads at VDD=3.3V.
Input and output Frequency Range
Power Supply Range (VDD)
High Drive Capability
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.
The SL23EP09NZ is designed to meet high drive
requirements for up to 30pF load condition per electrical
specifications tables.
If lower drive levels are required refer to SL2309NZ
fanout buffer product.
Contact SLI for 1.8V power supply Buffers and ZDB
products.
