9DB433AGILF

Overview

The Renesas Electronics 9DB433AGILF is a four-output PCIe Gen3 zero-delay buffer and fanout clock distribution IC. It operates within a supply voltage range of 3.135 V to 3.465 V, supporting maximum input frequencies up to 166 MHz and output frequencies up to 100 MHz. The device features differential HCSL signaling with a maximum propagation delay of 0 ps. Packaged in a 28-pin TSSOP, it functions across an operating temperature range of -40°C to +85°C, consuming approximately 170 mA of working power current.

Feature Summary

• Four differential HCSL output pairs designed for PCIe Gen3 applications
• Zero-delay buffer mode with 0 ps maximum propagation delay
• Supports input frequencies up to 166 MHz and output frequencies up to 100 MHz
• Operates on a single 3.3V supply (3.135 V to 3.465 V)

Applications

• PCI Express Gen3 clock distribution networks
• Backward compatible PCIe Gen2 and Gen1 system designs
• High-performance server and storage motherboard clocking

Procurement Notes

Verify the specific suffix 'AGILF' against official Renesas documentation to confirm package type and environmental compliance. Confirm that the 28-TSSOP variant matches the target PCB footprint requirements. Check for any recent Product Change Notices regarding assembly sites or marking changes before finalizing procurement orders.

Selection Notes

Select this component when a low-jitter, four-channel clock buffer is required for PCIe Gen3 interfaces. Ensure the design accommodates the 3.3V supply rail constraints and the thermal dissipation needs associated with 170 mA current consumption. Verify compatibility with upstream clock generators such as the 932S421 series for proper signal integrity.

Part Context

This part belongs to the 9DB433 family of clock buffers from Renesas Electronics. It serves as a specialized solution for high-speed serial interface timing, specifically targeting the stringent jitter requirements of PCI Express standards while maintaining backward compatibility with older generations.

Replacement Considerations

The 9DB433AFILF is a documented alternative offering SSOP-28 packaging instead of TSSOP-28. Designers must evaluate mechanical height differences and pin pitch variations between the two packages during replacement planning.
