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

The 843004I-01 is a 4 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 settings of 2 frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, 62.5MHz. The 843004I- • Four 3.3V differential LVPECL output pairs\n• Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended clock 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 – 2;
