ICS840014I
FEMTOCLOCKSCRYSTAL-TO-
LVCMOS/LVTTL FREQUENCY SYNTHESIZER
PRELIMINARY
GENERAL DESCRIPTION
The ICS840014I is a 4 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. This device uses a
26.5625MHz, 18pF parallel resonant crystal to synthesize
106.25MHz. Using FemtoClock’sTM ultra-low phase noise VCO
technology, the ICS840014I can achieve 1ps or lower typical
random rms phase jitter, easily meeting Fibre Channel jitter
requirements. The ICS840014I is packaged in a small 20-pin
TSSOP package.
