9DBV0741AKILF

Overview

The Renesas 9DBV0741AKILF is a seven-output, 1.8V PCIe fanout clock buffer designed for high-speed digital interfaces. It supports PCIe Gen1 through Gen3 standards with an operating frequency range of 1 MHz to 200 MHz. The device features integrated 100Ω terminations for direct connection to transmission lines, eliminating external resistors. It utilizes HCSL-compatible differential inputs and LP-HCSL outputs. Key electrical parameters include a typical power consumption of 50 mW and a supply voltage of 1.8V. The component is housed in a space-saving 5 mm x 5 mm 32-pin VFQFPN package.

Feature Summary

• Seven differential outputs with individual OE# pins for precise clock management
• Integrated 100Ω terminations allow direct connection to transmission lines
• Supports spread spectrum input for EMI reduction
• SMBus interface with selectable addresses for configuration optimization

Applications

• PCI Express (Gen1-Gen3) clock distribution systems
• High-performance computing platforms
• Server and storage infrastructure boards

Procurement Notes

Verify the specific suffix 'AKILF' against the manufacturer's current datasheet to confirm pinout and packaging details. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Ensure compatibility with legacy SMBus controllers if programmable features are utilized.

Selection Notes

Select this component when a 1.8V supply is available and seven buffered PCIe clock outputs are required. Compare against the 9DBV0541 (5-output) or 9DBV0941 (9-output) variants based on specific output count needs. Verify that the 1 MHz to 200 MHz frequency range meets the target system's timing requirements.

Part Context

This part belongs to the Renesas 9DBV05x1/07x1/09x1 family of ultra-low-power PCIe clock buffers. These devices are engineered to replace standard HCSL buffers by integrating termination resistors, thereby reducing board space and component count. The family shares common architectural features such as SMBus control and spread spectrum tolerance.

Replacement Considerations

Direct functional substitutes within the same family include the 9DBV0541AKILF (5 outputs) and 9DBV0941AKILF (9 outputs). Verify pin-to-pin compatibility and output enable configurations when substituting between different output counts.
