描述
The 844008I-01 is an 8 output LVDS synthesizer optimized to generate GbE/10GbE reference clock frequencies and is a member of the HiPerClocks™ family of high performance clock solutions. Using a 25MHz parallel resonant crystal, the following frequencies can be generated based on the F_SEL pin: 125MHz or 156.25MHz. The 844008I-01 uses our 3rd generation low phase noise VCO technology and can achieve <1ps typical rms phase jitter, easily meeting GbE/10GbE jitter requirements. The 844008I-01 is packaged in a 32-pin TQFP or 32 VFQFN packages.
