Product details

PCIe clock buffer with integrated PLL — 1:2 fanout at 1.5 V

The Renesas 9DBU0231AKLF is a 1:2 PCI Express (PCIe) clock buffer with an integrated PLL. 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.

Frequently asked questions

What is the exact specification of 9DBU0231AKLF?

Input is HCSL; output is LP-HCSL. 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.

What is the difference between 9DBU0231AKLF and 9DBU0231AKLFT?

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.

Is 9DBU0231AKLF lead-free?

Yes, it is ROHS3 compliant, which means it meets the lead-free directive.

What is the equivalent or replacement for 9DBU0231AKLF?

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.
