It accepts a standard HCSL input and delivers two LP-HCSL outputs. Maximum output frequency is 167 MHz. The part runs from a 1.425 V to 1.575 V supply. ## Supply rail and temperature — what they mean for the BOM The 1.425 V to 1.575 V supply range means the part fits boards that already have that rail. The operating temperature range is 0°C to 70°C — commercial grade. ## Lifecycle and sourcing No last-time-buy pressure.","metaTitle":"9DBU0231AKLF PCIe Clock Buffer, PLL, 167 MHz, 1.5 V, QFN","metaDescription":"9DBU0231AKLF PCI Express (PCIe) clock buffer with integrated PLL.

Maximum frequency is 167 MHz. Supply voltage is 1.425 V to 1.575 V. It has a 1:2 input-to-output ratio. Package is a 24-VFQFN with exposed pad (4x4 mm). Operating temperature is 0°C to 70°C. Differential input and output are both Yes."},{"question":"What is the difference between 9DBU0231AKLF and 9DBU0231AKLFT?","answer":"The suffix 'T' typically indicates Tape & Reel packaging. The 9DBU0231AKLF (no T) ships in a Tray. Electrically they are identical. Choose based on your assembly line's feeder preference."},{"question":"Is 9DBU0231AKLF lead-free?","answer":"Yes, it is ROHS3 compliant, which means it meets the lead-free directive."},{"question":"What is the equivalent or replacement for 9DBU0231AKLF?","answer":"There is no direct pin-compatible second source listed. The closest functional peer is the 9DB803DFLFT, which also has a PLL and targets PCIe, but its output is HCSL (not LP-HCSL) and its supply is 3.135 V. The 9DBL411BGLFT has LP-HCSL output but no PLL. Neither is a drop-in replacement; verify your board's supply rail and output level requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/9DBU0231AKLF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/9DBU0231AKLF when reusing this data.
