ICS840002
FEMTOCLOCKSCRYSTAL-TO-
LVCMOS/LVTTL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS840002 is a 2 output LVCMOS/LVTTL
Synthesizer optimized to generate Fibre Channel
reference clock frequencies and is a member of
the HiPerClocksTM 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_SEL1:0):
212.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, and
53.125MHz.The ICS840002 uses ICS’ 3rd generation low phase
noise VCO technology and can achieve 1ps or lower typical
rms phase jitter, easily meeting Fibre Channel jitter requirements.
The ICS840002 is packaged in a 16-pin TSSOP package.
