9DBU0831AKILFT

Overview

The Renesas 9DBU0831AKILFT is a clock buffer designed for PCI Express applications. It features two outputs and operates with a supply voltage range of 1.425V to 1.575V. The device supports frequencies up to 167MHz and consumes approximately 53mW in typical operation. It functions as a zero-delay buffer or fanout buffer, utilizing HCSL-compatible differential inputs and LP-HCSL differential outputs. The component is rated for an operating temperature range from -40°C to +85°C and is housed in a 40-VFQFPN package.

Feature Summary

• Two differential outputs supporting PCIe Gen1-Gen3 standards
• Low power consumption of 53mW typical
• Operates on 1.5V supply (1.425V ~ 1.575V)
• Supports frequencies up to 167MHz

Applications

• PCI Express clock distribution
• Zero-delay buffering for high-speed interfaces
• Fanout buffering for system clocks

Procurement Notes

Verify the specific suffix 'AKILFT' against the manufacturer's official datasheet to confirm pinout, packaging dimensions, and RoHS compliance status. Ensure the ordering quantity aligns with the manufacturer's standard reel size or minimum order requirements specified by authorized distributors. Cross-reference the part number with the latest Renesas documentation to avoid discrepancies between legacy IDT naming conventions and current Renesas specifications.

Selection Notes

Select this component when a low-power, two-output clock buffer is required for PCIe Gen1 through Gen3 systems. The 1.5V supply voltage makes it suitable for modern low-voltage logic families. Verify that the input signal matches the HCSL specification and that the output load requirements are compatible with LP-HCSL signaling. Consider the 40-VFQFPN package constraints for PCB layout if board space is limited.

Part Context

This part belongs to the Renesas (formerly IDT) ultra-low-power PCIe clock buffer family. It serves as a successor or alternative to similar IDT devices like the 9DBU0231, offering comparable functionality under the Renesas portfolio. The '9DBU' prefix typically denotes a dual-output buffer within this product line.

Replacement Considerations

Check for direct pin-to-pin replacements such as the 9DBU0231AKILFT if fewer outputs are acceptable. Verify compatibility with other members of the 9DBU series. Ensure any substitute maintains the same 1.5V supply requirement and LP-HCSL output characteristics.
