97U870AKLFT

Overview

The Renesas 97U870AKLFT is a clock driver and distribution integrated circuit designed for 1.8V DDR-II applications, featuring an integrated Phase-Locked Loop (PLL). Manufactured by Renesas Electronics Corporation, this component operates within the 97U870A series and utilizes a 40-pin VFQFPN package with exposed pad. It supports surface-mount installation and includes moisture sensitivity features. The device functions as a specialized clock generator tailored for memory subsystems requiring precise timing signals.

Feature Summary

• Integrated PLL for clock generation and distribution
• Designed specifically for 1.8V DDR-II memory interfaces
• Available in a compact 40-VFQFPN package
• Supports surface-mount technology (SMD/SMT) installation

Applications

• DDR-II memory system clock distribution
• Computer motherboard clock generation
• Server memory controller timing

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate that the product is no longer actively stocked or sold by major distributors such as Mouser. Verification of current availability requires direct consultation with authorized suppliers or secondary market vendors, as standard inventory data reflects discontinuation status rather than active supply.

Selection Notes

Engineers selecting this part must account for its discontinued status when designing new hardware. The 40-VFQFPN package dimensions and pinout should be verified against PCB footprints. Since the device is EOL, alternative components with compatible electrical specifications and package types should be evaluated to ensure long-term supply chain stability for production runs.

Part Context

The 97U870AKLFT belongs to the Renesas 97U870A family of clock drivers. This series focuses on providing stable clock signals for high-speed memory interfaces. The specific suffix 'KLFT' typically denotes lead-free packaging and tape-and-reel shipping configuration, aligning with RoHS compliance standards common in modern electronic manufacturing.

Replacement Considerations

As the 97U870AKLFT is discontinued, no official direct replacement part numbers are provided in the source data. Designers should consult Renesas technical support for recommended alternatives or evaluate third-party compatible clock generators that match the 1.8V DDR-II specification and 40-VFQFPN form factor.
