9DB403DGILFT

Overview

The Renesas Electronics 9DB403DGILFT is a PCI Express (PCIe) fanout buffer and zero-delay clock distribution IC. It accepts a single HCSL input and provides four differential outputs in LVDS or HCSL formats, supporting a maximum frequency of 400 MHz. The device operates 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 28-TSSOP package with a width of 4.40 mm and supports surface-mount installation.

Feature Summary

• Zero-delay buffering for PCIe Gen1/Gen2 applications
• Single HCSL input to four differential LVDS/HCSL outputs
• Maximum operating frequency of 400 MHz
• Integrated PLL for clock signal conditioning

Applications

• PCI Express (PCIe) clock distribution networks
• High-speed digital system timing solutions
• Server and storage infrastructure boards

Procurement Notes

Verify the suffix 'ILFT' confirms the industrial temperature grade (-40°C to +85°C) and tape-and-reel packaging format. Confirm RoHS3 compliance status through official manufacturer documentation prior to integration. Ensure the specific ordering code matches the required package variant to avoid pinout discrepancies.

Selection Notes

Select this component when a 1:4 fanout ratio is required for PCIe interfaces up to 400 MHz. The 28-TSSOP package is suitable for space-constrained designs requiring surface-mount technology. Verify that the system power supply remains strictly between 3.135 V and 3.465 V to maintain specified electrical performance.

Part Context

This part belongs to the 9DB403 series of clock buffers manufactured by Renesas Electronics. It serves as a specialized timing solution for high-speed serial link standards, specifically designed to drive multiple receivers from a single source while maintaining signal integrity and minimizing jitter in complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other members of the 9DB403 family, such as 9DB403DGLFT, noting differences in temperature range and packaging configuration.
