MPC9824AC

Overview

The MPC9824AC is a processor-specific clock generator designed for CPU, PowerQUICC, and telecom applications. It features a single circuit with LVCMOS input and output types, supporting crystal or LVCMOS inputs. The device generates outputs up to 200MHz with a fixed 2:8 division ratio. It operates on a 3.135V to 3.465V supply within an industrial temperature range of -40°C to 85°C. Packaged in a 32-LQFP (7x7mm) surface-mount case, it integrates PLL functionality for precise timing generation.

Feature Summary

• Integrated PLL for stable clock generation
• Fixed 2:8 input-to-output frequency ratio
• Supports LVCMOS and Crystal inputs
• Industrial temperature range (-40°C to 85°C)

Applications

• CPU clock generation
• PowerQUICC processor systems
• Telecom equipment timing

Procurement Notes

Verify the package designation matches the 32-LQFP form factor. Confirm the voltage supply range aligns with system requirements of 3.135V to 3.465V. Ensure the operating temperature specification meets the environmental conditions of the target application.

Selection Notes

Select this component when a fixed 2:8 division ratio is required for PowerQUICC or CPU interfaces. The LVCMOS I/O compatibility simplifies interface design compared to differential solutions. Verify that the 200MHz maximum frequency suffices for the target processor speed.
