9DB833AFILF

Overview

The 9DB833AFILF is an 8-output PCIe Gen3 zero-delay buffer and fanout clock distribution IC manufactured by Renesas Electronics. It operates with a maximum input frequency of 166 MHz and supports differential HCSL signaling for both input and output. The device functions within a supply voltage range of 3.135 V to 3.465 V and features a propagation delay of 0 ps. It is housed in a 48-BSSOP package (7.50 mm width) and is designed for high-speed clock distribution in PCI Express applications.

Feature Summary

• Supports PCIe Gen3 requirements while maintaining backward compatibility with Gen2 and Gen1 standards.
• Provides eight differential HCSL output pairs with phase jitter performance of less than 1 ps RMS for PCIe Gen3.
• Operates in zero-delay buffer mode or fanout mode, driven by differential SRC outputs from main clock generators.

Applications

• PCI Express Gen3 clock distribution systems
• Backward compatible PCIe Gen2 and Gen1 infrastructure
• High-speed data acquisition and processing boards
