Description
The ICS843004 is a 4 output LVPECL synthesizeroptimized to generate Fibre Channel referenceclock frequencies and is a member of the HiPerClocksTM family of high performance clocksolutions from IDT. Using a 26.5625MHz 18pFparallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL[1:0]):212.5MHz, 187.5MHz, 159.375MHz, 156.25, 106.25MHz, and 53.125MHz. The ICS843004 uses ICS' 3rd generation low phasenoise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Fibre Channel jitter requirements.The ICS843004 is packaged in a small 24-pin TSSOP package.
