MPC9448FAR2

Clock Buffers, Drivers Overview

The MPC9448FAR2 is a 3.3V or 2.5V compatible, 1:12 clock fanout buffer designed for high-performance clock tree applications. It features selectable LVCMOS and differential LVPECL compatible inputs, supporting maximum clock frequencies up to 350 MHz with output skews less than 150 ps. The device includes synchronous output stop functionality in the logic low state to eliminate runt pulses and provides high-impedance output control. It operates within an ambient temperature range of –40°C to +85°C and is housed in a 32-lead LQFP package.

Clock Buffers, Drivers Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm that the specific ordering suffix matches the required packaging format. Ensure all electrical parameters align with system requirements before procurement.

Clock Buffers, Drivers Selection Notes

Select based on input signal type (LVCMOS vs. LVPECL) and supply voltage (2.5V or 3.3V). Consider thermal management requirements for high-frequency operation. Verify compatibility with existing clock tree architecture and termination strategies.

Clock Buffers, Drivers Part Context

The MPC9448 is pin and function compatible but performance-enhanced compared to the MPC948. It belongs to the Motorola/NXP timing solutions family, specifically designed for low voltage LVCMOS clock distribution.

Clock Buffers, Drivers Replacement Considerations

The MPC948 is a compatible predecessor. Verify functional equivalence and performance enhancements when substituting. No other direct public substitutes are confirmed.
