Integrated Circuit Systems ICS840002I
The ICS840002I is a 2 output LVCMOS/LVTTL Synthesizer optimized to generate Fibre Channel HiPerClockS™ reference clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from ICS. The ICS840002I uses ICS’ 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Fibre Channel jitter requirements. The ICS840002I is packaged in a 16-pin TSSOP package.| Part No. | ICS840002I |
