9DB233AFLFT

Overview

The Renesas Electronics 9DB233AFLFT is a clock buffer designed for PCI Express (PCIe) applications, supporting Gen1, Gen2, and Gen3 standards. It features two outputs with a maximum input frequency of 110 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V and functions at temperatures between 0°C and +70°C. Packaged in a TSSOP-20 format, it provides signal distribution for high-speed serial interfaces.

Feature Summary

• Supports PCIe Gen1, Gen2, and Gen3 signaling rates
• Provides 2 differential outputs from a single input
• Operates on a 3.3V power supply (3.135V–3.465V)
• Available in a 20-TSSOP surface-mount package

Applications

• PCI Express system clock distribution
• Server and workstation motherboard timing
• High-performance computing infrastructure

Procurement Notes

Verify the specific suffix 'AFLFT' against official Renesas documentation to confirm pinout compatibility and electrical characteristics relative to other variants like AGILFT. Confirm RoHS compliance status and lead-free specifications directly from the manufacturer's datasheet before procurement.

Selection Notes

Select this component when a dual-output buffer is required for PCIe lanes operating up to Gen3 speeds. Ensure the design accommodates the 0°C to +70°C commercial temperature range and the TSSOP-20 footprint constraints.

Part Context

This part belongs to the 9DB233 family of zero-delay buffers. It serves as a signal driver to fan-out reference clocks to multiple PCIe endpoints, maintaining signal integrity across the bus.

Replacement Considerations

The 9DB233AGILFT is a documented alternative variant within the same family. Verify package and electrical parameter alignment before substitution.
