Ultra-Low Jitter Clock Generator Family With Two Independent PLLs - LMK03328

LMK03328 (ACTIVE)

Ultra-Low Jitter Clock Generator Family With Two Independent PLLs

 

Description

The LMK03328 device is an ultra-low-noise clock generator with two fractional-N frequency synthesizers with integrated VCOs, flexible clock distribution and 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, reduces BOM cost and board area, and improves reliability by replacing multiple oscillators and clock distribution devices. The ultra-low-jitter reduces bit error rate (BER) in high-speed serial links.
