The 2:12 input-to-output ratio means two clock sources can be muxed into the fanout tree — useful for redundant or failover clock architectures on a PCI Express backplane. Rated for 400 MHz maximum frequency with differential I/O on both input and output sides (Yes/Yes), this part sits squarely in the PCIe Gen1 through Gen3 reference clock domain. The LP-HCSL output type is the standard for PCIe clock distribution — no level translation needed between the buffer and the endpoint devices.","metaTitle":"Renesas 9ZML1255AKILF PCIe Clock Buffer, 2:12, 400 MHz","metaDescription":"Renesas 9ZML1255AKILF PCI Express clock fanout buffer. 2:12 ratio, LP-HCSL outputs, 400 MHz max, PLL, -40 to 85°C.
