LMK03328RHST Clock Synthesizer Jitter Cleaner Ultra-low jitter clock generator family

Description

The LMK03328 device is an ultra-low-noise clockgenerator with two fractional-N frequencysynthesizers

with integrated VCOs, flexible clockdistribution and fanout, and pin-selectableconfiguration states stored

in on-chip EEPROM. Thedevice can generate multiple clocks for various multigigabit serial interfaces and

digital devices, reducesBOM cost and board area, and improves reliability byreplacing multiple oscillators

and clock distributiondevices. The ultra-low-jitter reduces bit error rate(BER) in high-speed serial links.
