ICS840002I
FEMTOCLOCKSCRYSTAL-TO-
LVCMOS/LVTTL FREQUENCY SYNTHESIZER
GENERAL DESCRIPTION
The ICS840002I 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 ICS840002I 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 ICS840002I is packaged in a 16-pin TSSOP package.
