XR81111-CA04-F Datasheet - Exar Corporation

General Description
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.

FEATURES
• 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: <0.60ps
