ESCRIPTION
The ICS840002I is a 2 output LVCMOS/LVTTL
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_SEL1:0):
212.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, and
53.125MHz. The ICS840002I 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 ICS840002I is packaged in a 16-pin TSSOP package.
