9DB233AGILF

Overview

The Renesas Electronics 9DB233AGILF is a PCI Express (PCIe) fanout buffer and zero-delay clock distribution IC. It features a single differential input and two differential outputs, supporting PCIe Gen1, Gen2, and Gen3 standards with maximum frequencies up to 110 MHz. The device operates on a 3.3V supply voltage ranging from 3.135 V to 3.465 V. It utilizes a PLL-based architecture for low jitter performance and is housed in a 20-TSSOP surface-mount package. The component supports an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Zero-delay buffer architecture with integrated PLL for minimal skew
• Supports PCIe Gen1, Gen2, and Gen3 signaling standards
• Single differential input to two differential output configuration
• Operates within 3.135 V to 3.465 V supply voltage range

Applications

• PCI Express clock distribution in server platforms
• High-speed data acquisition systems requiring precise timing
• Industrial control equipment utilizing PCIe interfaces

Procurement Notes

Verify the suffix 'ILF' indicates the specific lead-free tape-and-reel packaging variant compatible with standard SMT assembly processes. Confirm that the 20-TSSOP footprint matches the target PCB layout dimensions. Ensure the selected distributor provides traceability documentation for RoHS compliance and REACH status as required by regulatory standards.

Selection Notes

Select this component when a single-source clock signal requires splitting into two matched paths with zero propagation delay relative to the input edge. The 110 MHz maximum frequency rating suits Gen1 through Gen3 PCIe applications. Consider the -40°C to +85°C temperature range against environmental conditions. Verify power supply stability within the 3.135 V to 3.465 V window to maintain specified jitter performance.
