97U2A877AHLFT

Application Specific Clock/Timing Overview

The Renesas 97U2A877AHLFT is a clock driver and distribution component belonging to the 97U877A series. It functions as a 1.8V DDR-II PLL clock driver designed for high-speed memory applications. The device features a 1:10 multiplication/division factor and supports a maximum output frequency of 370 MHz. It operates within a supply voltage range of 1.7 V to 1.9 V and draws a typical operating current of 300 mA. The component is housed in a CABGA-52 package, suitable for surface mount installation, and is rated for commercial temperature operation between 0°C and +70°C.

Application Specific Clock/Timing Feature Summary

• Integrated PLL clock driver optimized for 1.8V DDR-II memory systems
• Supports 1:10 frequency division with a maximum output frequency of 370 MHz
• Operates on a single 1.8V power supply (1.7V to 1.9V range)
• Available in a compact CABGA-52 surface-mount package

Application Specific Clock/Timing Applications

• DDR-II memory subsystem clock generation
• High-speed data acquisition systems requiring precise clock distribution
• Telecommunications equipment utilizing low-voltage differential signaling

Application Specific Clock/Timing Procurement Notes

The 97U2A877AHLFT is listed as an obsolete or end-of-life product by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors. Verify the specific suffix 'HLFT' against official datasheets to confirm tape-and-reel packaging and lead-free status before procurement.

Application Specific Clock/Timing Selection Notes

Select this component when designing systems requiring a dedicated 1.8V PLL clock driver for DDR-II interfaces. Ensure the design accommodates the 1.7V to 1.9V supply voltage window and the 300 mA current consumption. The CABGA-52 package requires appropriate PCB layout considerations for thermal management and signal integrity at frequencies up to 370 MHz.

Application Specific Clock/Timing Part Context

This part belongs to the Renesas 97U877A family of clock drivers. It shares core specifications with variants like the 97U877AHLF but may differ in packaging format or shipping quantity due to the 'T' suffix indicating reel packaging. It serves as a specialized timing solution for legacy DDR-II architectures rather than modern high-bandwidth memory standards.

Application Specific Clock/Timing Replacement Considerations

Direct replacements are limited due to the obsolete status. Evaluate other members of the 97U877A series or newer Renesas clock generator families that support DDR-II specifications. Verify pin compatibility and electrical parameters such as supply voltage and output frequency limits during substitution.
