98ULPA877AHILF

Application Specific Clock/Timing Overview

The 98ULPA877AHILF is a low-power clock driver and distribution component manufactured by Renesas Electronics. It functions as a PLL clock driver designed for DDR-I/II applications, operating with a 1:10 multiplication/division factor. The device supports a maximum output frequency of 410 MHz and requires a supply voltage between 1.7 V and 1.9 V. It draws approximately 300 mA during operation and is housed in a VFQFPN-40 package. The component operates within a temperature range of -40°C to +85°C and is classified as End-of-Life (EOL).

Application Specific Clock/Timing Feature Summary

Application Specific Clock/Timing Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and Mouser reports no sales in certain regions. Verification of current stock status through authorized distributors is required before procurement planning.

Application Specific Clock/Timing Selection Notes

Select this part only if the design specifically requires a 1.8V supply and DDR-I/II compatibility. Ensure the VFQFPN-40 footprint matches the PCB layout. Due to EOL status, alternative components with similar electrical specifications should be evaluated for new designs.

Application Specific Clock/Timing Part Context

The 98ULPA877AHILF belongs to the 98ULPA877A series of clock drivers. It shares functional similarities with the 98ULPA877AKILF variant but may differ in specific ordering suffixes or packaging details. Both variants are discontinued.

Application Specific Clock/Timing Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult Renesas for recommended obsolescence replacements or evaluate generic clock drivers with matching 1.8V and 410 MHz specifications.
