It takes a crystal input and produces up to three output clocks in either HCSL or LVCMOS format, with a maximum output frequency of 100 MHz. The 1:3 input-to-output ratio means one crystal feeds three clock lanes — enough for a small PCIe switch or a root complex with a few downstream ports. The part operates from a 1.7V to 1.9V supply rail and is rated over the -40°C to 85°C industrial temperature range, so it fits in both datacom equipment and outdoor-base-station line cards. ## Output standard flexibility — HCSL for PCIe, LVCMOS for general use The 9FGV0231AKILF supports both HCSL and LVCMOS output types. HCSL (High-Speed Current Steering Logic) is the standard signalling for PCIe reference clocks — if you are feeding a PCIe switch, root complex, or endpoint PHY, you want HCSL. LVCMOS is the fallback for non-PCIe clock distribution on the same board: FPGAs, Ethernet controllers, or generic logic that expects a rail-to-rail CMOS clock. The differential output is enabled only on the HCSL side (the input is single-ended crystal), so the LVCMOS outputs are single-ended. This dual-format capability lets one BOM line cover both the PCIe clock tree and the system-side fanout, reducing oscillator count. ## Supply and temperature — industrial-rated, low-voltage rail The 1.7V to 1.9V supply range is tighter than the typical 3.3V clock generator — this part runs from the 1.8V auxiliary rail common on server and networking motherboards. The -40°C to 85°C operating temperature range covers industrial environments: base stations, industrial PCs, test equipment, and outdoor edge gateways. ## Lifecycle status — active production, no EOL concern The 9FGV0231AKILF carries an Active product status with ROHS3 compliance. For a BOM freeze or a new design, this part is safe to qualify — no imminent obsolescence risk.","metaTitle":"9FGV0231AKILF PCIe Clock Generator, PLL, HCSL/LVCMOS, 100MHz","metaDescription":"Renesas 9FGV0231AKILF PCI Express clock generator with PLL, crystal input, HCSL/LVCMOS outputs up to 100 MHz.

The differential output is HCSL only."},{"question":"What is the output frequency range of 9FGV0231AKILF?","answer":"The maximum output frequency is 100 MHz. This covers PCIe Gen 1, 2, and 3 reference clock requirements (all 100 MHz). For higher-speed SerDes or memory interfaces, a different PLL with a higher ceiling would be needed."},{"question":"Does 9FGV0231AKILF require an external crystal?","answer":"Yes, the input is a crystal — the part does not have an integrated oscillator. The BOM needs an external crystal (typically 25 MHz or 100 MHz, depending on the PLL configuration) and its associated load capacitors."},{"question":"What is the equivalent or cross reference for 9FGV0231AKILF?","answer":"The closest functional peer in the same family is the 9ZXL0851EKKLF, which also targets PCIe clock generation with HCSL outputs but offers a 1:8 fanout at 400 MHz and runs from a 3.135V supply. The 9FGV0231AKILF is the lower-power, lower-voltage, lower-fanout option (1:3, 100 MHz, 1.8V rail). They are not pin-compatible — the package and supply differ — so a board redesign is required to swap between them."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/9FGV0231AKILF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/9FGV0231AKILF when reusing this data.
