MPC9351AC

Overview

The MPC9351AC is a programmable clock generator manufactured by Renesas Electronics, belonging to the MPC9351 series. It operates on a single 3.3V supply voltage and supports a maximum output frequency of 240 MHz with a maximum input frequency of 300 MHz. The device utilizes a Phase-Locked Loop (PLL) architecture to generate clock signals from LVCMOS or LVPECL inputs, producing LVCMOS outputs. It is housed in a 32-lead TQFP package designed for surface-mount installation. The component functions within an operating temperature range of 0°C to +70°C and is classified as moisture sensitive.

Feature Summary

• Supports FSL 1-9 configuration with LVCMOS/LVPECL inputs and LVCMOS outputs
• Maximum output frequency capability of 240 MHz
• Operates on a standard 3.3V power supply
• Available in a 32-TQFP surface-mount package

Applications

• Freescale PowerPC processor clock generation
• System peripheral clock sourcing
• General-purpose PLL clock generation in embedded systems

Procurement Notes

The MPC9351AC is listed as obsolete or end-of-life by major distributors such as Mouser Electronics. Availability is restricted, and direct procurement from the manufacturer may not be possible. Verification of current stock status through authorized channels is required before design finalization.

Selection Notes

Designers should verify the specific suffix requirements for packaging and temperature ranges, as the base part number corresponds to the commercial grade. Ensure that the input clock source matches the supported LVCMOS or LVPECL standards. Consider the 32-TQFP footprint constraints during PCB layout planning.

Part Context

This component is part of the MPC93R51/MPC9351 family of clock generators optimized for Freescale (now NXP) PowerPC architectures. It serves as a critical timing element for system synchronization in legacy embedded designs requiring precise clock distribution.

Replacement Considerations

Direct pin-to-pin replacements are not explicitly documented in public sources. Designers may need to evaluate newer VersaClock families or consult Renesas for specific cross-reference recommendations due to the discontinued status.
