9DB233AFILFT

Overview

The Renesas Electronics 9DB233AFILFT is a PCIe clock buffer featuring two differential outputs. It operates within a supply voltage range of 3.135 V to 3.465 V and supports maximum input frequencies up to 110 MHz. The device utilizes a TSSOP-20 package for surface mount installation. Designed for zero-delay buffering, it ensures precise clock distribution with a maximum propagation delay of 0 ps. The component functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Two differential HCSL outputs for PCIe Gen1/Gen2/Gen3 applications
• Zero-delay buffer architecture with 0 ps maximum propagation delay
• Operates at 3.3V nominal supply (3.135V–3.465V) with 110 MHz max frequency
• Available in 20-TSSOP package for SMD/SMT mounting

Applications

• PCI Express clock distribution buffers
• High-speed digital system timing solutions
• Server and storage backplane clocking

Procurement Notes

Verify the suffix 'A' indicates commercial temperature grade (0°C to +70°C), distinct from the industrial grade 'I' variant (-40°C to +85°C). Confirm RoHS compliance status via official datasheets. Ensure packaging type matches design requirements, as options include cut tape or reel formats.

Selection Notes

Select this model when two buffered PCIe clock outputs are required. Compare against the 9DB233AGILFT if an extended industrial temperature range is necessary. Verify that the 110 MHz frequency limit aligns with the target PCIe generation speed requirements.

Part Context

This component belongs to the 9DB233 series of PCI Express fanout buffers. It serves as a specific package variation within the family, distinguished by its commercial temperature rating and TSSOP-20 footprint compared to other available pinouts or thermal grades.

Replacement Considerations

The 9DB233AGILFT is a verified alternative offering identical electrical performance but with an extended industrial temperature range (-40°C to +85°C).
