840002 - Block Diagram
Description
The 840002 is a 2 output LVCMOS/LVTTL 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_SEL1:0): 212.5MHz, 159.375MHz, 156.25MHz, 106.25MHz, and 53.125MHz. The 840002 uses low phase noise VCO technology and can achieve 1ps or lower typical rms phase jitter, easily meeting Fibre Channel jitter requirements. The 840002 is packaged in a 16-pin TSSOP package.
