ESCRIPTION
The ICS840004-11 is a 4 output LVCMOS/
LVTTL 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, 125MHz and
62.5MHz can be generated based on one frequency select
pin (F_SEL). The ICS840004-11 uses ICS’ 3
rd
generation low
phase noise VCO technology and can achieve 1ps or lower
typical random rms phase jitter, easily meeting Ethernet jitter
requirements. The ICS840004-11 is packaged in a small
20-pin TSSOP package.
