It is designed to distribute low-jitter reference clocks for PCI Express and Ethernet interfaces in servers, switches, and base stations. The PLL provides jitter attenuation, cleaning up a noisy reference before fanout. Temperature grade is commercial: 0°C to 70°C. This part is intended for indoor, controlled-environment equipment — not suitable for outdoor, industrial, or automotive use without additional qualification. ## Active lifecycle — no end-of-life risk for new designs The 9DBV0831AKLF is listed as Active and ROHS3 compliant. ## How it compares to nearby Renesas clock buffers The 9DB803DFLFT is a 1:8 HCSL fanout buffer with PLL, but it runs at 400 MHz on a 3.135 V supply — a different voltage domain and higher speed tier. The 9DBL411BGLFT has no PLL and only a 1:4 fanout. It is a simpler fanout buffer, not a jitter-cleaning device.","metaTitle":"Renesas 9DBV0831AKLF Clock Buffer, 1:8 HCSL, 137.5 MHz","metaDescription":"Renesas 9DBV0831AKLF PLL clock buffer, 1:8 HCSL fanout, max 137.5 MHz for PCIe/Ethernet.

PCIe Gen3 typically uses a 100 MHz reference clock but with tighter jitter requirements. The integrated PLL helps with jitter cleaning, but you must verify that the jitter performance meets your Gen3 link budget. For Gen3/4 designs, consider the 9ZXL0851EKKLF which runs at 400 MHz and has industrial temperature range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/9DBV0831AKLF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/9DBV0831AKLF when reusing this data.
