8422002I-07中文资料FemtoClock® Crystal-to-LVHSTL Frequency Synthesizer数据手册Renesas规格书

描述 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.
