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.
