MPC93H51ACR2

Overview

The MPC93H51ACR2 is a programmable PLL clock generator manufactured by Renesas Electronics. It operates on a single 3.3V supply and supports LVCMOS and LVPECL input signals, generating LVCMOS outputs. The device features a maximum output frequency of 240 MHz and accepts input frequencies up to 300 MHz. It is housed in a 32-LQFP surface-mount package with dimensions of 7x7 mm. The component functions within an operating temperature range of 0°C to +70°C and carries a Moisture Sensitivity Level (MSL) rating of 3.

Feature Summary

• PLL Clock Generator IC with 2:11 input-to-output ratio
• Supports LVCMOS and LVPECL inputs with LVCMOS outputs
• Maximum output frequency of 240 MHz
• 32-LQFP (7x7 mm) surface-mount package

Applications

• Freescale PowerPC processor clock generation
• System timing for embedded controllers
• Clock distribution in industrial equipment

Procurement Notes

This component has been officially discontinued and is no longer in production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer allocation. Buyers must confirm the authenticity of stock and review datasheet revisions carefully, as specifications may have evolved prior to end-of-life notification.

Selection Notes

Designers requiring this specific part number must account for its discontinued status during procurement planning. Alternative components from the same family or newer generations should be evaluated for pin compatibility and electrical equivalence. Verify that the replacement supports the required 3.3V supply voltage and LVCMOS/LVPECL interface standards necessary for the target application.

Part Context

The MPC93H51ACR2 belongs to the MPC93H51 series of clock generators designed primarily for Freescale (now NXP) PowerPC-based systems. It provides flexible clock synthesis capabilities for processors and peripherals. The 'R2' suffix indicates tape-and-reel packaging, while 'AC' typically denotes the commercial temperature grade and specific speed binning within the product line.
