FemtoClock-Crystal-to-LVDS Frequency Synthesizer

The 844002-01 is a 2 output LVDS 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 844002-01 uses IDT' ·Two differential LVDS outputs\n·Selectable crystal oscillator interface or single-ended LVCMOS/LVTTL input\n·Supports the following output frequencies: 156.25MHz, 125MHz, 62.5MHz\n·VCO range: 560MHz – 680MHz\n·RMS phase jitter @ 156.25MHz, using a 25MHz crystal (1.875MHz – 20MHz): 0.41ps (typical)\;
