9DB833AGILFT

Overview

The 9DB833AGILFT is an 8-output PCIe Gen1-2-3 zero delay and fanout buffer manufactured by Renesas Electronics. It operates with a supply voltage range of 3.135 V to 3.465 V and supports input frequencies up to 166 MHz in bypass mode. The device features eight differential HCSL output pairs with phase jitter performance below 1 ps RMS for PCIe Gen3. It utilizes a 48-pin TSSOP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports PCIe Gen1, Gen2, and Gen3 standards with backward compatibility
• Provides eight differential 0.7V HCSL output pairs
• Operates in Zero Delay Buffer (ZDB) and Fanout modes
• Accepts spread spectrum input signals

Applications

• PCI Express clock distribution networks
• Server and storage system clocking
• High-speed digital interface buffering

Procurement Notes

Verify the specific suffix 'GILFT' against official Renesas documentation to confirm package type, lead finish, and environmental compliance status. Ensure the selected variant matches the required thermal grade and moisture sensitivity level for the target assembly process.

Selection Notes

Select this component when eight differential outputs are required for PCIe Gen3 applications. Compare against the 9DB833AFLFT if the older SSOP package is preferred, noting that the AGILFT uses a TSSOP package. Verify input frequency requirements, as PLL mode operation is limited to 50-110 MHz while bypass mode supports up to 166 MHz.

Part Context

This part belongs to the 9DB833 series of high-performance clock buffers designed specifically for PCI Express systems. It serves as a critical timing element in multi-lane PCIe architectures, ensuring signal integrity and low jitter across multiple endpoints.

Replacement Considerations

The 9DB833AFLFT is listed as a similar alternative but utilizes a 48-BSSOP package instead of TSSOP. Other family members like the 9DB433AGILFT offer fewer outputs (4) and may not fit designs requiring eight channels.
