ESCRIPTION
The ICS843004 is a 4 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, 156.25, 106.25MHz, and
53.125MHz. The ICS843004 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 ICS843004 is packaged in a small 24-pin TSSOP package.
