8421002I-01中文资料FemtoClock Crystal-to-HSTL Frequency Synthesizer数据手册Renesas规格书

描述 Description

The 8421002I-01 is a 2 output HSTL synthesizer optimized to generate Ethernet reference clock frequencies and is a member of the HiPerClocks™ family of high performance clock solutions. Using a 25MHz, 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz and 62.5MHz. The 8421002I-01 uses our 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Ethernet jitter requirements. The 8421002I-01 is packaged in a small 20-pin TSSOP package.
