843004 - Block Diagram
Description
The 843004 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 2 frequency select pins (F_SEL[1:0]): 212.5MHz, 187.5MHz, 159.375MHz, 156.25, 106.25MHz, and 53.125MHz. The 843004 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 843004 is packaged in a small 24-pin TSSOP package.
