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.
