ESCRIPTION
The ICS840024I is a 4 output LVCMOS/LVTTL
Synthesizer optimized to generate Ethernet
reference clock frequency and is a member of the
HiPerClocks
TM
family of high performance clock
solutions from ICS. The ICS840024I uses ICS’ 3
rd
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.
