It accepts a single-ended LVCMOS or crystal input and produces a differential HCSL or LVDS output at up to 100 MHz, with a 1:1 input-to-output ratio. The part operates from a 3.135 V to 3.465 V supply and is rated over the industrial temperature range of -40°C to 85°C, making it suitable for outdoor telecom cabinets and factory-floor controllers that see thermal cycling. ## Differential output, single-ended input — plan the input conditioning The input side is not differential — it accepts LVCMOS or a crystal — so the board designer needs to provide a clean single-ended reference or a fundamental-mode crystal. The output side is differential (HCSL or LVDS), which is what the PCIe reference clock receiver expects. The 1:1 ratio means one input drives one output; no fanout inside this package. ## Package and footprint Housed in a 16-lead VFQFN with exposed pad (3 mm × 3 mm body), surface-mount only. The exposed pad must be soldered to a ground plane for thermal and electrical performance. Standard QFN reflow profile applies; MSL level is not in this record, so verify the moisture sensitivity label on the reel before opening the bag. ## Active, ROHS3, no end-of-life concern Renesas lists the 5V41234NLGI as Active with ROHS3 compliance.","metaTitle":"5V41234NLGI PCIe Clock Generator, PLL, 100 MHz, 16-QFN","metaDescription":"5V41234NLGI PCI Express clock generator with integrated PLL. 100 MHz max, HCSL/LVDS outputs, -40 to 85°C.
