9DB233AGILFT

Overview

The Renesas Electronics 9DB233AGILFT is a PCI Express (PCIe) fanout buffer and zero-delay clock distribution IC. It features one differential input and two differential outputs, operating at frequencies up to 110 MHz. The device utilizes HCSL output signaling and supports a supply voltage range of 3.135 V to 3.465 V. Packaged in a 20-TSSOP format with a pitch of 4.40 mm, it is designed for low jitter applications compliant with PCIe Gen1 through Gen3 standards.

Feature Summary

• PCIe Zero-Delay Buffer: Aligns REF input phase and frequency with CLKOUT signals using PLL technology.
• Differential I/O: Supports one differential HCSL input and two differential HCSL outputs.
• Frequency Range: Operates from 10 MHz to 110 MHz in PLL mode.
• Low Jitter Performance: Designed to meet strict timing requirements for high-speed communication systems.

Applications

• PCI Express (PCIe) Gen1, Gen2, and Gen3 clock distribution networks.
• High-performance communication systems requiring precise clock alignment.
• Server and workstation motherboard clocking architectures.

Procurement Notes

Verify the specific suffix 'ILFT' against the manufacturer's current datasheet to confirm package dimensions and temperature grade. Ensure compatibility with the target PCB footprint for the 20-TSSOP package. Confirm RoHS compliance status as per the latest environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a single differential source requires splitting into two matched differential loads with minimal skew. Verify that the system power supply remains within the 3.135 V to 3.465 V range. Consider the 20-TSSOP package constraints if board space is limited compared to larger packages like QFN or BGA.

Part Context

This part belongs to the 9DB233 series of PCIe clock buffers. It serves as a critical timing element in systems where clock integrity is paramount. The 'A' typically denotes an advanced revision or specific binning, while 'ILFT' indicates the industrial temperature range and tape-and-reel packaging format.

Replacement Considerations

Direct pin-to-pin replacements may include other Renesas 9DB233 variants with different suffixes indicating package or temperature changes. Cross-vendor equivalents require careful verification of HCSL swing levels and PLL bandwidth characteristics to ensure signal integrity is maintained.
