9DMV0431AKILF

Overview

The 9DMV0431AKILF is a PCIe clock multiplexer and buffer manufactured by Renesas Electronics. It supports PCI Express Gen 1 through Gen 5 standards, operating at frequencies up to 200 MHz. The device features a 2:4 input-to-output ratio with differential LVDS inputs and LP-HCSL outputs. Powered by a single 1.8V supply, it operates within an industrial temperature range of -40°C to +85°C. Packaged in a compact 24-VFQFPN (4x4 mm) format, the IC integrates selectable asynchronous or glitch-free switching modes for flexible system design.

Feature Summary

• Supports PCIe Gen 1–5 Common Clocked (CC), Separate Reference no Spread (SRnS), and Separate Reference Independent Spread (SRIS) architectures
• Provides selectable asynchronous or glitch-free switching modes
• Features 2 differential LVDS inputs and 4 LP-HCSL outputs
• Operates on a single 1.8V power supply

Applications

• PCIe switch and retimer reference clock distribution
• Server and storage backplane clocking
• High-performance computing systems requiring SRIS/CC compliance

Procurement Notes

Verify the specific suffix 'AKILF' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the 24-VFQFPN package. Check for any recent Product Change Notifications (PCNs) regarding material or assembly process updates before finalizing procurement orders.

Selection Notes

Select this component when designing for PCIe Gen 1–5 interfaces requiring low jitter and flexible switching capabilities. It is suitable for applications needing direct connection to transmission lines without external termination resistors. Compare against the 9DML04 series if a 3.3V supply voltage is required instead of 1.8V.

Part Context

This part belongs to Renesas' comprehensive family of PCIe clocking solutions designed for high-speed serial interface compliance. It addresses the growing demand for separate reference independent spread (SRIS) clocking in modern data center infrastructure. The device complements other members like the 9DMU and 9DBV series by offering specific mux functionality optimized for multi-lane PCIe topologies.

Replacement Considerations

The 9DMV0431BKILF is listed as a manufacturer-recommended alternative. Verify pinout and electrical parameter equivalence before substitution. No other public cross-model substitutes are confirmed in available documentation.
