Universal Clock - High Frequency LVCMOS Clock Synthesizer General Description The XR81101-AA02 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 LVCMOS output. The device is optimized for use with a 25MHz crystal (or system clock) and generates a 125MHz output clock for GE applications. The LVCMOS output has very low phase noise jitter of sub 150fs, while consuming extremely low power. 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/eliminat...
