98ULPA877AKLF

Application Specific Clock/Timing Overview

The Renesas 98ULPA877AKLF is a low-power, 1.8V DDR-II PLL clock driver belonging to the 98ULPA877A series. It functions as a clock distribution component with a 1:10 multiplication/division factor and supports maximum output frequencies up to 410 MHz. The device operates within a supply voltage range of 1.7 V to 1.9 V and draws approximately 300 mA of operating current. Designed for surface mount installation, it is housed in a VFQFPN-40 package and maintains an operational temperature range from -40°C to +85°C.

Application Specific Clock/Timing Procurement Notes

The 98ULPA877AKLF is listed as End-of-Life (EOL) by Renesas Electronics. Availability is restricted, and distributors may not stock this item in all regions. Verification of lifecycle status and alternative sourcing 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 design accommodates the 1.7V to 1.9V supply constraint and the specific thermal requirements of the VFQFPN-40 package within the -40°C to +85°C industrial temperature range.

Application Specific Clock/Timing Part Context

This part belongs to the Renesas 98ULPA877A family of clock drivers. It shares specifications with variants such as the 98ULPA877AHILF, differing primarily in ordering suffixes or minor manufacturing lot details. The family targets low-power timing solutions for high-speed digital interfaces.

Application Specific Clock/Timing Replacement Considerations

As an EOL product, direct replacements are limited. Engineers should evaluate newer Renesas timing ICs or cross-reference with compatible DDR-II clock generators from other manufacturers, ensuring pin compatibility and electrical parameter alignment.
