Exar Corporation XR81102
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.| Part No. | XR81102 |

GENERAL DESCRIPTION
The application diagram below shows a typical synthesizer configuration with any standard crystal oscillating in fundamental mode. Internal load capacitors are optionally available to minimize/eliminate external crystal loads. A system clock can also be used to overdrive the oscillator for a synchronous timing system. The typical phase noise plot below shows the jitter integrated over the 1.875MHz to 20MHz range that is widely used in WAN systems. These clock devices show a very good high freq
