MPC942CACR2

Overview

The MPC942CACR2 is a clock distribution integrated circuit manufactured by Renesas Electronics Corporation. It functions as an LVCMOS fanout buffer with a single circuit and a 1:18 input-to-output ratio. The device supports LVCMOS and LVTTL inputs, providing LVCMOS outputs. It operates at a maximum frequency of 250MHz with a supply voltage range of 2.375V to 3.465V. Designed for surface mount installation, it is housed in a 32-LQFP package (32-TQFP 7x7 supplier device package). The component is specified for an operating temperature range of 0°C to 70°C and targets Intel CPU server applications.

Procurement Notes

This component is identified as a discontinued product. Availability is restricted, and Mouser indicates the product is not currently sold in certain regions. Verification of current stock status and alternative sourcing channels is required before procurement planning.

Selection Notes

Select this part for designs requiring a 1:18 LVCMOS clock distribution buffer. Ensure the system operates within the 0°C to 70°C temperature range and utilizes a 2.375V to 3.465V power supply. Verify compatibility with LVCMOS or LVTTL input sources and confirm that the 32-LQFP package fits the PCB layout constraints.

Part Context

The MPC942CACR2 belongs to the Renesas clock driver and distribution category. It is specifically designed for high-speed clock signal buffering and splitting in server environments. The device provides a single circuit to distribute a clock signal to up to 18 loads, maintaining signal integrity for LVCMOS logic families.

Replacement Considerations

The product status is listed as discontinued. Designers should evaluate equivalent 1:18 LVCMOS fanout buffers from current Renesas portfolios or other manufacturers. Verify pin compatibility, electrical specifications, and package dimensions when selecting a replacement.
