MPC9446FA

Clock Buffers, Drivers Overview

The MPC9446FA is a clock fanout buffer, divider, and multiplexer integrated circuit manufactured by Renesas Electronics. It features a 2:10 input-to-output ratio, supporting LVCMOS input and output logic levels. The device operates with a supply voltage range of 2.375V to 3.465V and supports maximum frequencies up to 250 MHz. Designed for surface mount installation, it is housed in a 32-LQFP package (specifically identified as 32-TQFP 7x7 in supplier documentation). The component functions within an operating temperature range of -40°C to 85°C.

Clock Buffers, Drivers Feature Summary

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'FA' against official Renesas documentation to confirm pinout, packaging dimensions, and electrical characteristics, as suffixes often denote package type or temperature grade variations. Ensure compatibility with the required 32-LQFP footprint during PCB layout. Confirm availability status directly with authorized distributors, as lead times may vary based on production cycles.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source needs to drive ten separate loads with LVCMOS compatibility. Ensure the design environment maintains the specified 2.375V–3.465V supply range. Verify that the 250 MHz maximum frequency meets the system's timing requirements. Consider the 32-LQFP package constraints for thermal management and board space allocation.

Clock Buffers, Drivers Part Context

The MPC9446FA belongs to the MPC9446 family of clock buffers and multiplexers from Renesas Electronics. This series is designed for applications requiring precise clock distribution and signal conditioning. The part serves as a specialized timing solution within the broader category of clock and timer ICs, distinct from general-purpose logic buffers.
