XR81102EVB Datasheet - Exar Corporation

General Description
The XR81101-CA02 is a clock synthesizer operating at a 3.3V/2.5V supply with Integer divider, using a 25MHz parallel resonant crystal reference input provides a 125MHz LVPECL outputs. The device is optimized for use with a 25MHz crystal (or system clock) and generates a 125MHz output clock for GE applications. The LVPECL outputs have very low phase noise jitter of sub 150fs, while consuming extremely low power.
