97U877AHLFT

Overview

The Renesas 97U877AHLFT is a DDR-II PLL clock driver and distributor designed for memory applications. It operates within a supply voltage range of 1.7 V to 1.9 V and supports maximum output frequencies up to 370 MHz. The device features a 1:10 multiplication/division factor and utilizes SSTL-18 output signaling. It is housed in a 52-CABGA package with dimensions of 4.5x7.0 mm. The component functions as a zero-delay buffer, ensuring minimal input-to-output skew for high-speed data synchronization.

Feature Summary

• Integrated PLL for low-jitter clock generation
• 1:10 input-to-output frequency ratio
• SSTL-18 compatible outputs
• 52-CABGA surface mount package

Applications

• DDR-II memory subsystems
• High-speed data acquisition systems
• Server and storage controller clock distribution

Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging versus tray configurations. Confirm current lifecycle status, as related variants such as the 97U877AHLF are listed as discontinued. Ensure compliance with RoHS directives by checking the detailed environmental declaration provided by the manufacturer.

Selection Notes

Select this component when designing DDR-II interfaces requiring precise clock alignment. Verify that the system power supply strictly maintains the 1.7 V to 1.9 V range to ensure stable operation. Consider the 52-CABGA footprint constraints during PCB layout. Compare performance metrics against newer successors if long-term availability is a critical design requirement.
