Its 800 MHz maximum output frequency covers the common SerDes reference clock range — 156.25 MHz, 312.5 MHz, and 625 MHz — with margin for the PLL loop bandwidth to attenuate upstream jitter before the signal reaches the transceiver. The dual PLLs with bypass let one path clean a noisy reference while the other generates a separate frequency domain, or bypass the PLL entirely for a clean-through mode when the input is already low-jitter. The base product number LMK05318 covers multiple output-format and package variants — confirm the full RGZR suffix matches the BOM line before committing.","metaTitle":"Texas Instruments LMK05318RGZR Clock Synchronizer, 800 MHz","metaDescription":"Texas Instruments LMK05318RGZR clock synchronizer & jitter cleaner, 800 MHz max, dual PLL with bypass, 2:8 I/O, 48-VQFN.
