ESCRIPTION
The ICS8422004I-01 is a 4 output LVHSTL
Synthesizer optimized to generate Ethernet
reference clock frequencies and is a member
of the HiPerClocks
TM
family of high
performance clock solutions from ICS. Using
a 25MHz 18pF parallel resonant crystal, the following
frequencies can be generated based on the 2 frequency
select pins (F_SEL[1:0]): 156.25MHz, 125MHz and
62.5MHz. The ICS8422004I-01 uses ICS’ 3
rd
generation
low phase noise VCO technology and can achieve 1ps or
lower typical rms phase jitter, easily meeting Ethernet jitter
requirements. The ICS8422004I-01 is packaged in a small
24-pin TSSOP package.
F
EATURES
