9DB233AGLFT

Overview

The Renesas Electronics 9DB233AGLFT is a zero-delay fanout buffer designed for PCI Express (PCIe) applications, supporting Gen1 through Gen3 standards. It features one differential input and two differential outputs with HCSL signaling. The device operates within a supply voltage range of 3.135 V to 3.465 V and supports maximum input frequencies up to 110 MHz. Packaged in a 20-TSSOP format, it ensures minimal propagation delay while maintaining signal integrity for high-speed clock distribution.

Feature Summary

• Zero-delay buffering architecture for PCIe Gen1-Gen3 clock distribution
• Single differential input driving two differential outputs
• HCSL output signaling compatible with standard PCIe receivers
• Operates on 3.3V nominal supply (3.135V–3.465V)

Applications

• PCI Express root complex clock distribution
• Switch fabric clocking in server platforms
• High-performance computing motherboard designs

Procurement Notes

Verify the suffix 'GLFT' corresponds to the lead-free, tape-and-reel packaging variant. Confirm RoHS compliance status via the manufacturer's current datasheet, as regulatory statuses may change. Ensure the specific package tolerance matches the PCB footprint requirements for the 20-TSSOP form factor.

Selection Notes

Select this component when a 1:2 split ratio is required for PCIe clock trees. Compare against the 9DB233AGILFT variant if an extended industrial temperature range (-40°C to +85°C) is necessary, as the GLFT version is specified for commercial temperatures (0°C to +70°C).

Part Context

This part belongs to the 9DB233 family of PCIe clock buffers. It serves as a distribution element in multi-lane or multi-device PCIe architectures. The 'A' grade typically denotes specific electrical performance characteristics defined by Renesas for this generation of timing solutions.

Replacement Considerations

The 9DB233AGILFT is a verified alternative offering an extended operating temperature range. Other members of the 9DB233 series may provide different pinouts or electrical specs; verify compatibility before substitution.
