Description

The 843002 is a 2 output LVPECL synthesizer optimized to generate Fibre Channel reference clock frequencies. 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 843002 uses our 3rd generation low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Fibre Channel jitter requirements. The 843002 is packaged in a small 20-pin TSSOP package.
