Description

The 843004I is a 4 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 two frequency select pins (F_SEL[1:0]): 212.5MHz, 187.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, and 53.125MHz. The 843004I 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 843004I is packaged in a small 24-pin TSSOP package.
