9DB401CGLF

Overview

The Renesas Electronics Corporation 9DB401CGLF is a PCI Express (PCIe) fanout buffer and distribution IC designed for zero-delay buffering applications. It features a single input to four output configuration with a maximum operating frequency of 400MHz. The device accepts HCSL differential inputs and provides both HCSL and LVDS differential outputs. It operates within a supply voltage range of 3.135V to 3.465V and is housed in a 28-TSSOP package with a width of 4.40mm. The component includes an internal PLL and supports surface-mount installation.

Feature Summary

• PCI Express fanout buffer with 1:4 input-to-output ratio
• Zero-delay buffering capability with integrated PLL
• Supports differential HCSL inputs and mixed HCSL/LVDS outputs
• Maximum frequency operation up to 400MHz

Applications

• PCI Express clock distribution networks
• System timing solutions requiring zero-delay buffering
• High-speed digital interface clock generation

Procurement Notes

Verify the specific suffix 'CGLF' against official Renesas documentation to confirm package type, temperature range, and RoHS compliance status. Confirm current manufacturing status as this part number may be subject to End-of-Life notices or production changes documented in Product Change Notices.

Selection Notes

Select this component when a PCIe application requires a single source clock to drive four destinations with minimal skew. Ensure the design supports the required 3.135V to 3.465V supply voltage and accommodates the 28-TSSOP footprint. Verify that the target system environment falls within the specified commercial temperature range if the standard variant is selected.

Part Context

This component belongs to the 9DB401 family of clock buffers manufactured by Renesas Electronics. It serves as a specialized timing solution for high-speed serial interfaces, specifically optimized for the electrical requirements of PCI Express standards. The device replaces discrete buffer solutions to reduce board space and signal integrity issues.
