9DBV0231AKILFT

Application Specific Clock/Timing Overview

The 9DBV0231AKILFT is a PCIe clock buffer and driver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 1.7V to 1.9V and supports maximum frequencies up to 167MHz. The device features one differential HCSL input and two differential LP-HCSL outputs, providing a 1:2 fanout ratio. Packaged in a 24-pin VFQFPN (4x4mm) with an exposed pad, it is designed for surface mount installation. The component includes integrated PLL functionality and is rated for commercial operating temperatures between 0°C and 70°C.

Application Specific Clock/Timing Feature Summary

• Supports PCIe Gen1/Gen2/Gen3 applications with frequencies up to 167MHz
• Converts HCSL differential input to low-power HCSL (LP-HCSL) differential outputs
• Integrates a Phase-Locked Loop (PLL) for jitter attenuation
• Configurable via strapping pins without requiring an SMBus interface

Application Specific Clock/Timing Applications

• PCI Express (PCIe) root complex clock distribution
• Peripheral slot clock generation
• High-speed digital system timing

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'AKILFT' against official Renesas documentation to confirm package type, tape-and-reel quantity, and RoHS compliance status. Ensure the procurement source provides valid traceability for the 24-VFQFPN package. Confirm moisture sensitivity level (MSL) ratings prior to soldering processes.

Application Specific Clock/Timing Selection Notes

Select this component when a single HCSL source must drive two LP-HCSL loads in a PCIe architecture. The LP-HCSL output signaling reduces power consumption and board space compared to standard HCSL. Verify that the system requires a 1.8V nominal supply and fits within the 0°C to 70°C temperature range.

Application Specific Clock/Timing Part Context

This part belongs to the IDT Ultra-Low-Power (ULP) PCIe family, now under Renesas Electronics. It serves as a zero-delay buffer or fanout buffer for high-speed serial interfaces. The device replaces legacy clock generators by integrating PLL and buffering functions into a compact footprint.
