ICS840008AR01 Datasheet PDF - Integrated Circuit Systems

GENERAL DESCRIPTION
The ICS840008-01 is an 8 output LVCMOS/LVTTL Synthesizer designed to generate 125MHz for Gigabit Ethernet applications and is a member of the HiPerClocksTM 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.
