9DBV0731AKILFT

Overview

The 9DBV0731AKILFT is a PCIe fanout clock buffer manufactured by Renesas Electronics. It features seven differential outputs and operates with a single 1.8V supply voltage. The device supports input frequencies up to 250MHz and includes integrated terminations for direct connection to 100Ω transmission lines. It utilizes HCSL input and output signaling standards. The component is housed in a 48-lead VFQFPN package measuring 6.0 x 6.0 mm. It is designed for high-performance timing applications requiring low jitter and precise clock distribution.

Feature Summary

• Seven differential outputs with individual enable pins
• Integrated 100Ω termination resistors for direct line connection
• Supports SMBus configuration with selectable addresses
• Operates on a single 1.8V power supply

Applications

• PCI Express (PCIe) system clock distribution
• High-speed data acquisition systems
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix 'AKILFT' against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm moisture sensitivity level and reflow soldering profile requirements prior to assembly. Ensure compatibility with existing PCB footprint designs for the 48-VFQFPN package.

Selection Notes

Select this component when seven differential clock outputs are required for PCIe or similar high-speed interfaces. Compare performance metrics such as jitter and skew against alternative models like the 9DBV0531 or 9DBV0941 based on specific channel count needs. Verify that the 1.8V operating voltage aligns with the target system's power architecture.

Part Context

This part belongs to the 9DBV0x31 family of PCIe clock buffers from Renesas. The family provides various output configurations ranging from five to nine channels. These devices are engineered to meet the stringent timing requirements of modern high-speed serial interfaces, offering flexibility through programmable features and robust signal integrity characteristics.

Replacement Considerations

Direct replacements within the same family include the 9DBV0531AKILFT for fewer outputs or the 9DBV0941AKILFT for more outputs. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Note that Renesas timing products have transitioned to SiTime; consult current availability and support channels.
