9DBL0643ANDGI8

Overview

The 9DBL0643ANDGI8 is a zero-delay/fanout buffer IC from Renesas Electronics, designed for PCI Express applications. It supports PCIe Gen 1 through Gen 5 standards and features a single input to six outputs configuration. The device operates within a supply voltage range of 3.135V to 3.465V and functions at frequencies up to 200MHz. It utilizes HCSL signaling for both differential inputs and outputs. The component is housed in a 40-VFQFPN package with an exposed pad, measuring 5x6mm, and is rated for industrial temperatures from -40°C to +85°C.

Feature Summary

• Supports PCIe Gen 1 through Gen 5 signal integrity requirements
• Provides Loss of Signal (LOS) indicator functionality
• Delivers zero-delay buffering with low skew performance

Applications

• PCI Express clock distribution networks
• High-speed digital interface timing synchronization
• Server and storage system backplanes

Procurement Notes

Verify the specific suffix GI8 against official Renesas documentation to confirm the exact package dimensions and tape-and-reel specifications. Ensure compatibility with RoHS3 compliance requirements for your assembly process. Cross-reference the part number with authorized distributors to confirm current lifecycle status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring precise clock distribution for multi-lane PCIe interfaces. It is suitable for applications needing signal fan-out with minimal propagation delay variation. Consider the 40-pin VFQFPN footprint for PCB layout constraints. Verify that the operating temperature range meets the environmental demands of the target deployment scenario.

Part Context

This part belongs to the 9DBL series of clock buffers and generators from Renesas. These devices are engineered for high-performance computing and communication infrastructure. The series typically includes variants supporting different output counts and signaling standards, providing designers with flexible options for complex timing architectures in modern electronic systems.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic cross-references may not match the specific LOS functionality or PCIe Gen 5 electrical characteristics required for this application.
