The clock redriver uses a phase locked loop to generate a few identical clock signals for use by the DRAM chips on the module. This same tech is also used for clock multipliers and dividers throughout digital systems. Rambus has details on their "DDR5 client clock driver" here: https://www.rambus.com/memory-interface-chips/ddr5-client-dimm-chipset/ddr5-ckd/ https://www.rambus.com/memory-interface-chips/ddr5-client-di...
