3 Description
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 BOM cost and board area and improving reliability by replacing multiple oscillators and clock distribution devices. The ultra-low jitter reduces biterror rate (BER) in high-speed serial links.
