Integrated Circuit Systems ICS840004
The ICS840004 is a 4 output LVCMOS/LVTTL IC S Synthesizer optimized to generate Ether net HiPerClockS™ reference clock frequencies and is a member of the HiPerClocks TM family of high performance clock solutions from IDT. The ICS840004 uses IDT’s 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical random r ms phase jitter, easily meeting Ethernet jitter requirements. The ICS840004 is packaged in a small 20-pin TSSOP package.| Part No. | ICS840004 |
