ICS840024I
FEMTOCLOCKSCRYSTAL-TO-
LVCMOS/LVTTL FREQUENCY SYNTHESIZER
PRELIMINARY
GENERAL DESCRIPTION
The ICS840024I is a 4 output LVCMOS/LVTTL
Synthesizer optimized to generate Ethernet
reference clock frequency and is a member of the
HiPerClocksTM family of high performance clock
solutions from ICS. The ICS840024I uses ICS’ 3rd
generation low phase noise VCO technology and can achieve
1ps or lower typical random rms phase jitter, easily meeting
Ethernet jitter requirements. The ICS840024I is packaged in a
small 20-pin TSSOP package.
