Texas Instruments LMK03328RHSR

Description
The LMK03328 is an ultra-low-noise clock generator with two fractional-N frequency synthesizers with integrated VCOs, 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, 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.
