FemtoClock? Crystal-to-3.3V,2.5V LVPECL Frequency Synthesizer

The 843002I-01 is a 2 output LVPECL synthesizer optimized to generate Ethernet reference clock frequencies. Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, and 62.5MHz. The 843002I- 01 uses; ·Two 3.3V or 2.5V LVPECL outputs\n·Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input\n·Supports the following output frequencies: 156.25MHz, 125MHz and 62.5MHz\n·VCO range: 560MHz - 680MHz\n·RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz-20MHz): 0.55ps (typica;
