FemtoClock® Crystal-to-3.3V LVPECL Frequency Synthesizer

The 843002-01 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 843002-01 uses IC • Two 3.3V LVPECL outputs\n• Selectable crystal oscillator interface or LVCMOS single-ended input\n• Supports the following input 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): 0.54ps (typical)\n• Typic;
