MPC940LACR2

Overview

The MPC940LACR2 is a clock fanout buffer manufactured by Renesas Electronics Corporation, designed for Intel CPU server applications. It operates with a maximum frequency of 250MHz and accepts LVCMOS or LVPECL inputs to produce LVCMOS outputs. The device features a 2:18 input-to-output ratio within a single circuit configuration. It supports differential signaling capabilities despite the specific output type listed as LVCMOS. Power supply requirements range from 2.375V to 3.465V, and it functions within an operating temperature range of 0°C to 70°C. The component is housed in a 32-LQFP package.

Feature Summary

Procurement Notes

Verify the exact ordering suffix R2 against official Renesas documentation to confirm packaging variations such as tape-and-reel specifications. Confirm current availability status as previous listings for similar MPC940 variants indicate potential end-of-life notices. Ensure compatibility with existing board designs regarding the 32-LQFP footprint and voltage levels before procurement.

Selection Notes

Select this component when a 2:18 fanout ratio is required for Intel CPU servers using LVCMOS or LVPECL sources. Ensure the system power supply falls within the 2.375V to 3.465V range. Verify that the 32-LQFP package fits the PCB layout constraints. Consider the 250MHz maximum frequency limit relative to the target clock signal speed.
