9DBU0831AKLF

Overview

The 9DBU0831AKLF is a clock buffer manufactured by Renesas Electronics, designed for high-performance timing applications. It features two outputs with LP-HCSL signaling and supports input frequencies up to 150 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V and consumes typical power of 53 mW. Packaged in a compact 48-VFQFPN format, it is suitable for PCIe Gen1-Gen3 environments. Operating temperatures range from 0°C to +70°C, ensuring reliability in commercial settings.

Feature Summary

• Two differential outputs with LP-HCSL signaling
• Supports PCIe Gen1, Gen2, and Gen3 standards
• Low power consumption of 53 mW typical
• Operates on 3.3V supply (3.135V–3.465V)

Applications

• PCI Express Gen1/Gen2/Gen3 clock distribution
• Server and storage system timing
• High-speed interface buffering

Procurement Notes

Verify RoHS compliance status via official datasheets before integration. Confirm moisture sensitivity level (MSL) handling requirements during storage and assembly. Check for recent Product Change Notifications (PCN) regarding package or material updates. Ensure ordering suffixes match specific temperature or packaging variants if required by design specifications.

Selection Notes

Select this component when low-power buffering for PCIe Gen1-3 is required. Compare against the 9ZXL0831AKLF for higher output count options. Verify that the LP-HCSL output swing matches downstream receiver requirements. Ensure the 48-pin VFQFPN footprint fits the PCB layout constraints.

Part Context

Part of the Renesas 9DBU series, which focuses on low-power clock buffers for PCI Express applications. This model specifically addresses Gen1-3 compatibility needs with minimal power draw compared to older generation buffers.

Replacement Considerations

The 9ZXL0831AKLF is a related alternative offering eight outputs instead of two. Verify pinout compatibility and electrical parameter differences before substitution.
