ESCRIPTION

The ICS843002 is a 2 output LVPECL synthesizer

optimized to generate Fibre Channel reference

HiPerClockS™

clock frequencies and is a member of the

HiPerClocks

family of high performance clock

solutions from ICS. Using a 26.5625MHz, 18pF

parallel 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, 106.25MHz, and

53.125MHz. The ICS843002 uses ICS’ 3

generation low

phase noise VCO technology and can achieve 1ps or lower

typical rms phase jitter, easily meeting Fibre Channel jitter

requirements. The ICS843002 is packaged in a small 20-pin

TSSOP package.

EATURES
