ESCRIPTION
The ICS843002-01 is a 2 output LVPECL
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
ICS843002-01 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
ICS843002-01 is packaged in a small 20-pin TSSOP package.
