The integrated PLL can be bypassed when you need a clean fanout buffer instead of a synthesized frequency. With a maximum output frequency of 312.5 MHz, this part sits in the clock tree for 10G/25G Ethernet switches, wireless base station line cards, and high-speed data-converter reference clocks where jitter budgets are tight and the board needs one device to handle multiple logic families. ## 2:12 fanout and signal-format flexibility The 2:12 input-to-output ratio means a single 8V41N012NLGI replaces what might otherwise be a PLL plus a separate fanout buffer, saving board area and reducing the number of crystal oscillators on the bill. The input stage accepts both differential (HCSL, LVDS, LVHSTL, LVPECL) and single-ended (LVCMOS, LVTTL, crystal) references, so the same BOM line works across designs that use a discrete oscillator and designs that take a clock from a backplane or an FPGA. The twelve outputs are individually programmable to HCSL, LVCMOS, or LVTTL, which lets you drive a mix of SerDes reference clocks and lower-speed logic clocks from one device without external level translators. ## Industrial temperature and supply tolerance Rated for -40°C to 85°C operation, the 8V41N012NLGI is specified for outdoor telecom cabinets, factory-floor Ethernet switches, and base stations where the ambient temperature inside the enclosure can climb well above room temperature. The supply range of 3.135 V to 3.465 V gives you ±5% margin around a 3.3 V rail, which is typical for most intermediate-bus converters. If your board runs a 2.5 V or 1.8 V clock section, this part needs a separate 3.3 V rail — it is not a multi-voltage-core device. The 72-VFQFN package with an exposed pad requires a thermal via pattern under the paddle for heat sinking; the datasheet's recommended land pattern is worth following closely because the pad also serves as the ground return for the high-frequency outputs. ## Lifecycle and sourcing reality The 8V41N012NLGI carries an Active product status and ROHS3 compliance. There is no NRND flag, no last-time-buy notice, and no successor part number published — this is a current-production device that qualifies for new designs and production ramps without an obsolescence clock ticking. If you are dual-sourcing a clock generator for a high-volume build, this part is still in the Renesas active portfolio, so the supply channel is stable.","metaTitle":"8V41N012NLGI Clock Generator, FemtoClock NG, 312.5MHz","metaDescription":"Renesas 8V41N012NLGI FemtoClock NG clock generator.

The supply range is 3.135 V to 3.465 V, which covers a nominal 3.3 V rail, and the maximum output frequency is 312.5 MHz.
