Description
The ICS840002 is a 2 output LVCMOS/LVTTL Synthesizer optimized to generate Fibre Channel reference clock frequencies and is a member of the HiPerClocksTM family of high performance clock solutions from IDT. Using a 26.5625MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL1:0): 212.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, and 53.125MHz. The ICS840002 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 ICS840002 is packaged in a small 16-pin TSSOP package.
