97U877AKLF

Overview

The Renesas Electronics 97U877AKLF is a clock driver and distribution component designed for 1.8V DDR-II applications, featuring an integrated PLL. It operates within a supply voltage range of 1.7 V to 1.9 V and supports a maximum output frequency of 370 MHz. The device utilizes a CABGA-52 package and functions at a multiplication/division factor of 1:10. It draws 300 mA during operation and is rated for commercial temperatures between 0°C and +70°C. This component is classified under Clock Drivers & Distribution ICs.

Feature Summary

• Integrated PLL for 1.8V DDR-II clock generation
• Maximum output frequency of 370 MHz
• CABGA-52 surface-mount package
• 1:10 multiplication/division ratio

Applications

• DDR-II memory systems
• High-speed digital circuit clock distribution

Procurement Notes

The 97U877AKLF is listed as an End-of-Life (EOL) product by Renesas Electronics. Availability is restricted, and it may not be sold in all regions through standard distributors like Mouser. Verification of current stock status and EOL notices is required before procurement planning.

Selection Notes

Select this component for designs requiring a dedicated 1.8V DDR-II clock driver with PLL capabilities. Ensure the PCB layout accommodates the CABGA-52 package. Verify that the system power supply strictly adheres to the 1.7 V to 1.9 V operating range to maintain signal integrity and device functionality.

Part Context

This part belongs to the 97U877A series of clock drivers. It shares functional similarities with other DDR-II clock solutions from Renesas but is distinguished by its specific 370 MHz frequency limit and CABGA-52 packaging. It serves as a specialized solution for memory interface timing requirements.

Replacement Considerations

As an EOL product, direct substitutes are limited. Review the 97U877AHLF or other members of the 97U877A family for potential pin-compatible alternatives, though package differences (e.g., VFQFPN vs CABGA) must be evaluated carefully.
