Texas Instruments offers its LMK03318 ultra-low-jitter clock generator family with single PLL
Image of Texas Instruments’ LMK03318 Ultra-Low-Jitter Clock GeneratorTexas Instruments’ LMK03318 is an ultra-low-noise PLLatinum? clock generator with one fractional-N frequency synthesizer with integrated VCO, 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, thus reducing BOM cost and board area and improving reliability by replacing multiple oscillators and clock distribution devices. The ultra-low-jitter reduces bit-error rate (BER) in high-speed serial links.
