9DB833AFLF

Overview

The Renesas 9DB833AFLF is a PCIe Gen3 zero-delay buffer and fanout clock distribution IC. It accepts a single differential HCSL input and provides eight differential HCSL outputs. The device supports frequencies up to 166 MHz in bypass mode and operates within a supply voltage range of 3.135 V to 3.465 V. Packaged in a 48-BSSOP (SSOP) with a 7.50 mm width, it features a propagation delay of 0 ps maximum. The component is designed for high-speed clock distribution in systems requiring backward compatibility with PCIe Gen2 and Gen1 standards.

Feature Summary
