LMK03318 - Texas Instruments

LMK03318 Ultra-Low-Noise Jitter Clock Generator

The LMK03318 device is an ultra-low-noise PLLATINUM™ clock generator with one fractional-N frequency synthesizer with integrated VCO, flexible clock distribution and fanout, and pin-selectable configuration states stored in on-chip EEPROM. The device can generate multiple clocks for various multigigabit serial interfaces and digital devices, thus reducing BO.
