9DB433AGILFT

Overview

The Renesas Electronics 9DB433AGILFT is a PCI Express (PCIe) fanout buffer and zero-delay buffer (ZDB) designed for high-speed clock distribution. It features one differential HCSL input and four differential HCSL output pairs, packaged in a 28-TSSOP housing. The device supports maximum frequencies of 166 MHz, with an operating supply voltage range of 3.135 V to 3.465 V. It is RoHS compliant and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Four differential HCSL output pairs for PCIe clock distribution
• Zero-delay buffer mode with phase jitter < 1ps rms for PCIe Gen3
• Supports spread spectrum modulation input
• Available in 28-TSSOP surface-mount package

Applications

• PCI Express Gen1/Gen2/Gen3 clock distribution
• High-performance communication systems
• Server and storage backplane designs

Procurement Notes

Verify the suffix ILFT indicates tape-and-reel packaging when ordering. Confirm the specific assembly site and date code on the datasheet or manufacturer documentation to ensure compliance with current manufacturing standards. Check for any Product Change Notifications (PCNs) regarding package or material updates before finalizing procurement.

Selection Notes

Select this component for applications requiring low-jitter clock distribution for PCIe interfaces up to Gen3 speeds. Ensure the design accommodates the 3.3V nominal supply voltage and the thermal requirements of the TSSOP-28 package. Verify that the system architecture supports the differential HCSL signaling standard used by this buffer.

Part Context

This part belongs to the 9DB433 family of zero-delay buffers from Renesas. It serves as a successor or variant to earlier ICS branded parts, maintaining compatibility with PCIe specifications. The AGILFT designation specifies the commercial/industrial temperature grade, lead-free status, and reel packaging format.

Replacement Considerations

Direct pin-compatible replacements may include other members of the 9DB433 family, such as the 9DB433AGLF (tube packaging). Verify electrical parameters and package dimensions against the original design requirements before substitution.
