ESCRIPTION
The ICS840002-01 is a 2 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, the following frequencies can be
generated based on the 2 frequency select pins (F_SEL1:0):
156.25MHz, 125MHz, and 62.5MHz. The ICS840002-01 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 ICS840002-01 is
packaged in a small 16-pin TSSOP package.
