It takes a single-ended crystal input and produces up to nine differential HCSL or single-ended LVCMOS output copies at frequencies up to 100 MHz. The 1:9 input-to-output ratio means one clean reference fans out to nine PCIe lanes or endpoints — exactly what a multi-slot backplane or a switch-fabric card needs. The commercial temperature range (0°C to 70°C) suits controlled indoor equipment — server motherboards, network switches, storage arrays, and testers. For extended-temperature or outdoor deployment, look at the -40°C to 85°C rated 9ZXL0851EKKLF or 9ZXL1231EKILF instead. ## Output type and PCIe generation support The differential input-to-output flag reads No/Yes — meaning the crystal input is single-ended, but all nine clock outputs are differential (HCSL). That conversion is exactly what a PCIe clock tree needs: clean differential distribution from a low-cost crystal source.","metaTitle":"9FGV0841AKLF PCIe Clock Generator, 100 MHz, 48-VFQFPN","metaDescription":"9FGV0841AKLF PCI Express clock generator IC from Renesas.

The HCSL outputs are the primary PCIe reference clock signals; LVCMOS can drive legacy logic or sideband clocks on the same die."},{"question":"Is 9FGV0841AKLF available in tape and reel packaging?","answer":"The base order code 9FGV0841AKLF ships in a Tray. The tape-and-reel variant uses the suffix 'T' — 9FGV0841AKLFT — and is electrically identical. Confirm the reel suffix before ordering for pick-and-place feeders."},{"question":"Can 9FGV0841AKLF be used for PCIe Gen4 clocking?","answer":"The part is rated to 100 MHz maximum, which is the standard PCIe reference clock frequency for Gen1 through Gen3. Gen4 at 16 GT/s typically requires tighter phase-jitter specifications; verify against your root-complex or switch device's jitter tolerance mask before committing the BOM for a Gen4-only design."},{"question":"What is 9FGV0841AKLF's listed PLL status?","answer":"The PLL field is Yes — this is a PLL-based clock generator, not a simple buffer or fanout. The internal PLL synthesizes the output clocks from the crystal input."},{"question":"What is 9FGV0841AKLF's listed input type?","answer":"The input is a Crystal. The part accepts a fundamental-mode crystal as its reference, not a single-ended clock or differential oscillator. This keeps the BOM cost low by using a passive crystal rather than an active oscillator module."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/9FGV0841AKLF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/9FGV0841AKLF when reusing this data.
