98ULPA877AHI

Application Specific Clock/Timing Overview

The Renesas 98ULPA877AHI is a low-power, 1.8V DDR-II PLL clock driver designed for high-speed memory applications. It operates within a supply voltage range of 1.7 V to 1.9 V and supports maximum output frequencies up to 410 MHz. The device features a 1:10 multiplication/division factor and utilizes a VFQFPN-40 package. It functions as a clock distribution component with a single clock input and multiple clock outputs, suitable for demanding timing requirements in computing systems.

Application Specific Clock/Timing Feature Summary

• Low power 1.8V operation with 1.7 V to 1.9 V supply range
• DDR-II PLL clock driver architecture
• Maximum output frequency of 410 MHz
• VFQFPN-40 surface mount package

Application Specific Clock/Timing Applications

• DDR-II memory subsystems
• High-speed computing platforms
• Clock distribution networks requiring low skew

Application Specific Clock/Timing Procurement Notes

The 98ULPA877AHI is listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and alternative sourcing options is required before procurement planning.

Application Specific Clock/Timing Selection Notes

Select this component for designs requiring a dedicated 1.8V DDR-II clock driver with 10 outputs. Ensure the system environment supports the -40°C to +85°C operating temperature range. Verify that the VFQFPN-40 package footprint matches the PCB layout constraints.

Application Specific Clock/Timing Part Context

This part belongs to the 98ULPA877A series of clock drivers from Renesas Electronics. It is specifically engineered for low-power applications involving DDR-II memory interfaces, distinguishing it from higher voltage or non-PLL variants within the broader clock timing IC portfolio.

Application Specific Clock/Timing Replacement Considerations

As an EOL product, direct substitutes are limited. Review the 98ULPA877AKILF variant for potential pin-compatible alternatives, though functional equivalence must be verified against specific design requirements.
