840002I Description
The 840002I 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.
