The LMK03328 device is an ultra-low-noise clock generator that has two fractional-N frequency synthesizers with integrated VCOs, flexible clock distribution and fan-out, and pin-selectable configuration states stored in an on-chip EEPROM. The device can generate multiple clocks for various multi-gigabit serial interfaces and digital devices, which can reduce the BOM cost and board area, and can improve reliability by replacing multiple oscillators and clock distribution devices. The ultra-low-jitter reduces bit error rate (BER) in high-speed serial links.
