9DB1233AGLFT

Overview

The 9DB1233AGLFT is a PCI Express zero-delay buffer and multiplexer IC manufactured by Renesas Electronics. It features a single input to twelve output configuration with a maximum frequency of 166MHz. The device operates on a supply voltage ranging from 3.135V to 3.465V and utilizes HCSL signaling for outputs. It is housed in a 64-TSSOP package (0.240 inch width) and supports a commercial operating temperature range of 0°C to 70°C. The integrated PLL ensures precise clock distribution.

Feature Summary

• Zero-delay buffering with integrated PLL for phase alignment
• 1:12 input-to-output ratio supporting high-speed clock distribution
• HCSL differential output signaling compliant with PCIe standards
• Operates within 3.135V to 3.465V supply voltage range

Applications

• PCI Express clock distribution systems
• High-speed communication equipment requiring low jitter
• Server and storage system timing architectures

Procurement Notes

Verify the specific suffix 'GLFT' corresponds to the tape and reel packaging format as indicated in component databases. Confirm RoHS compliance status through official Renesas documentation prior to integration. Ensure the 64-TSSOP footprint matches the target PCB layout specifications exactly.

Selection Notes

Select this component when a single reference clock must be distributed to twelve destinations with minimal skew. The 166MHz maximum frequency suits Gen1 and Gen2 PCIe applications. Consider the 64-pin package density for board space constraints compared to lower-pin-count alternatives.

Part Context

This part belongs to the 9DB1233 family of zero-delay buffers. It serves as a critical timing element in complex digital systems where clock integrity is paramount. The device replaces discrete buffer solutions, reducing component count and improving signal reliability in high-speed data paths.
