Description
General part information
844004I-104 Series
The 844004I-104 is a 4 output LVDS 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, 106.25MHz and 53.125MHz. The 844004I-104 uses our third generation low phase noise VCO technology and can achieve <1ps typical rms phase jitter, easily meeting Fibre Channel jitter requirements. The 844004I-104 is packaged in a 32-pin VFQFN package.
