FemtoClock® Crystal-to-LVDS Frequency Synthesizer

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 ·Four differential LVDS outputs\n·Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended input\n·Supports the following output frequencies: 212.5MHz, 187.5MHz, 159.375MHz, 106.25MHz and 53.125MHz\n·VCO range: 560MHz - 680MHz\n·RMS phase jitter at 212.5MHz (637kHz – 10MHz), using a 26.5;
