Ultra-Low Jitter Clock Generator Family With Single PLL - LMK03318

LMK03318 (ACTIVE)

Ultra-Low Jitter Clock Generator Family With Single PLL

 

Description

The LMK03318 is an ultra-low-noise PLLatinumTM clock generator with one fractional-N frequency synthesizer with integrated VCO, flexible clock distribution/fanout, and pin-selectable configuration states stored in on-chip EEPROM. The device can generate multiple clocks for various multi-gigabit 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 bit-error rate (BER) in high-speed serial links.
