XR81111-CA04TR-F

XR81111 Universal Clock - High Frequency LVPECL Clock Synthesizer General Description FEATURES The XR81111-CA04 is a clock synthesizer with Integer divider, LVPECL driver, 3.3V/2.5V supply, taking a 25MHz Xtal input and providing one of four selectable output frequencies. The device is optimized for use with a 25MHz crystal (or system clock) and generates a selection of output frequencies 156.25MHz for 10GE/XAUI, 150MHz for SAS, 125MHz for GE and 100MHz for PCIe applications. • XR81111-CA04: Factory Configured • Footprint compatible with 5mm x 7mm differential oscillators • One differential LVPECL output pair • Crystal oscillator interface which can also be overdriven using a single-ended reference clock • Output frequency range: 100MHz - 156.25MHz • Crystal/input frequency: 25MHz, parallel resonant crystal • VCO range: 2GHz - 3GHz • RMS phase jitter @ 156.25MHz, 12kHz - 20MHz:
