It accepts a differential or single-ended input and produces eight differential HCSL outputs at up to 400 MHz, making it suitable for distributing reference clocks across multiple PCIe slots or QPI links in server and workstation chipsets. ## Industrial temperature grade — wider deployment than commercial peers There is no last-time-buy window, no NRND flag, and no announced end-of-life. For dual-sourcing or second-source qualification, the 9ZXL0851EKKLF shares the same 1:8 HCSL topology, 400 MHz ceiling, and industrial temperature range — a drop-in candidate for supply resilience, though its pinout should be verified against the board layout.","metaTitle":"Renesas 9ZXL0831EKILF PCIe QPI Clock Generator, 400MHz","metaDescription":"Renesas 9ZXL0831EKILF PLL clock generator for Intel QPI and PCI Express. 400MHz max, 1:8 HCSL outputs, 3.135–3.465V supply, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PLL":"Yes","Input":"Clock","Output":"HCSL","Package":"Tray","Main Purpose":"Intel QPI, PCI Express (PCIe)","Mounting Type":"Surface Mount","Package / Case":"48-VFQFN Exposed Pad","Frequency - Max":"400MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.135V ~ 3.465V","Number of Circuits":"1","Ratio - Input:Output":"1:8","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"48-VFQFPN (6x6)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.84","priceTiers":[{"qty":1,"price":"$5.84000","currency":"USD"},{"qty":10,"price":"$5.24700","currency":"USD"},{"qty":25,"price":"$4.96080","currency":"USD"},{"qty":80,"price":"$4.29938","currency":"USD"},{"qty":230,"price":"$4.07887","currency":"USD"},{"qty":490,"price":"$3.65996","currency":"USD"},{"qty":980,"price":"$3.47360","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7e5943f48d00bf4cec2899c8f002e5b1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/9ZXL0831EKILF/alternatives.json"},"ai":{"faq":[{"question":"What is the function of 9ZXL0831EKILF?","answer":"It is a PLL-based clock generator that produces eight HCSL outputs from one reference clock, purpose-built for Intel QPI and PCI Express interfaces.
