ESCRIPTION
The ICS8421004I-01 is a 4 output HSTL
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 ICS8421004I-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 ICS8421004I-01 is
packaged in a small 24-pin TSSOP package.
