General Description

The 8422002I-07 is a 2 output LVHSTL Synthesizer optimized to

generate Fibre Channel reference clock frequencies and is a

member of the 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_SEL[1:0]): 212.5MHz, 187.5MHz, 159.375MHz,

106.25MHz and 53.125MHz. The 8422002I-07 uses IDT’s 3rd

generation low phase noise VCO technology and can achieve 1ps

or lower typical rms phase jitter, easily meeting Fibre Channel jitter

requirements. The 8422002I-07 is packaged in a 20-pin TSSOP,

EPad package.
