9DBU0941AKLF Description

Short technical summary and product information.

The Renesas 9DBU0941AKLF is a 1:9 fanout buffer designed for PCI Express (PCIe) clock distribution. It accepts HCSL or LVDS differential inputs and provides nine LP-HCSL outputs. The device operates from a 1.425 V to 1.575 V supply and supports clock frequencies up to 167 MHz. It is a non-PLL buffer, ensuring low additive jitter for PCIe Gen1/2/3 applications.

 

The buffer is housed in a 48-VFQFN Exposed Pad package (48-VFQFPN 6x6 mm) and is surface mount compatible. The operating temperature range is 0°C to 70°C, making it suitable for commercial environments. The differential input and output architecture maintains signal integrity over typical motherboard trace lengths.

 

This part is ideal for use in desktop and server platforms where multiple PCIe slots require a clean, buffered reference clock. The 1:9 ratio allows a single input to drive up to nine loads, simplifying clock tree design.
