It accepts CML or LVDS differential inputs and delivers LVDS differential outputs, with the full signal path being differential throughout. That 1.2 GHz ceiling covers most high-speed serial link clocks (PCIe Gen3/4 reference, 10GbE, Fibre Channel) without margin pressure. The 2:4 ratio lets a single input fan out to four destinations, or two inputs can be multiplexed onto four outputs — useful when switching between a primary and redundant clock source without an external mux. ## Supply rails and temperature grade The device operates from two supply ranges: 1.71 V to 1.89 V (nominally 1.8 V) and 2.1 V to 2.7 V (nominally 2.5 V). The dual-rail architecture keeps core and output stages on separate planes, reducing noise coupling into the LVDS outputs. No AEC-Q grade is listed, so it is not qualified for automotive deployment. Packaged in a 16-lead VFQFPN measuring 3 mm × 3 mm with an exposed pad for thermal dissipation. Supplied in tube packaging — not tape-and-reel. For automated pick-and-place, plan for tube feeders or a bulk-to-tape conversion step.","metaTitle":"Renesas 8P34S1204NLGI 2:4 Fanout Buffer, 1.2 GHz, LVDS","metaDescription":"Renesas 8P34S1204NLGI active fanout buffer/mux, 2:4 ratio, 1.2 GHz max, LVDS output, CML/LVDS input, 16-VFQFPN, -40 to 85°C.
