ESCRIPTION
The ICS840008-01 is an 8 output LVCMOS/LVTTL
Synthesizer designed to generate 125MHz for
Gigabit Ethernet applications and is a member of
the HiPerClocks
TM
family of high performance clock
solutions from ICS. The ICS840008-01 uses ICS’
3rd generation low phase noise VCO technology and can achieve
1ps or lower typical random rms phase jitter, easily meeting
Gigabit Ethernet jitter requirements. The ICS840008-01 is
packaged in a small 24-pin SSOP package.
