ESCRIPTION
The ICS843002 is a 2 output LVPECL synthesizer
optimized to generate Fibre Channel reference
clock frequencies and is a member of the
HiPerClocks
TM
family of high performance clock
solutions from ICS. Using a 26.5625MHz, 18pF
parallel resonant crystal, the following frequencies can be
generated based on the 2 frequency select pins (F_SEL[1:0]):
212.5MHz, 187.5MHz, 159.375MHz, 106.25MHz, and
53.125MHz. The ICS843002 uses ICS’ 3
rd
generation low
phase noise VCO technology and can achieve 1ps or lower
typical rms phase jitter, easily meeting Fibre Channel jitter
requirements. The ICS843002 is packaged in a small 20-pin
TSSOP package.
