Outputs are individually selectable between HCSL and LVDS, which simplifies BOM consolidation when mixing PCIe and non-PCIe differential receivers on the same board. The differential input and all outputs are fully differential (Yes/Yes), so no single-ended termination is needed on the clock lanes. ## Lifecycle and compliance It is ROHS3 compliant, so it meets the EU RoHS exemption-free requirements for lead-free assembly.","metaTitle":"9DB403DFLF PCIe Buffer, 400 MHz, 1:4 Fanout, 28-SSOP","metaDescription":"Renesas 9DB403DFLF PCIe clock buffer with PLL, 400 MHz max, 1:4 HCSL/LVDS outputs, 3.3V supply, 28-SSOP.
