MPC93R52FA

Overview

The MPC93R52 is a 3.3 V LVCMOS zero-delay clock generator designed for high-performance telecom, networking, and computing applications. It features an integrated PLL capable of generating output frequencies from 16.67 MHz to 240 MHz with maximum output skew below 200 ps. The device provides 11 configurable outputs divided into three banks (QA, QB, QC), supporting frequency multiplication ratios of 3, 2, 1, 3/2, 2/3, 1/3, and 1/2 relative to the input reference clock. It operates within an ambient temperature range of 0°C to +70°C and utilizes a 32-lead LQFP package.

Feature Summary

• Configurable 11-output LVCMOS PLL clock generator with zero-delay buffer capability
• Output frequency range of 16.67 MHz to 240 MHz with maximum skew under 200 ps
• Integrated PLL requiring no external loop filter components
• Supports multiple frequency multiplication ratios including 3x, 2x, 1x, 3/2x, 2/3x, 1/3x, and 1/2x

Applications

• High-performance telecom systems
• Networking infrastructure equipment
• Computing applications requiring precise clock distribution

Procurement Notes

Verify the specific ordering suffix against the datasheet requirements. The 'FA' suffix indicates a standard 32-lead LQFP package, while the 'AC' suffix denotes a lead-free version of the same package. Confirm that the required voltage levels and environmental specifications align with the 3.3 V LVCMOS and 0°C to +70°C operating range defined in the technical data.

Selection Notes

Select this component when a low-skew, multi-output clock distribution solution is required for 3.3 V logic systems. Ensure the application can accommodate the separate analog power supply pin (VCCA) and implement the recommended RC filtering to minimize jitter. Verify that the desired output frequencies fall within the supported ranges for the chosen feedback divider configuration.

Part Context

The MPC93R52 belongs to Freescale Semiconductor's Advanced Clock Drivers Devices family. It is functionally compatible with the MPC952. The manufacturer, originally Freescale Semiconductor, has since been acquired by NXP Semiconductors.

Replacement Considerations

The MPC952 is identified as a pin and function compatible alternative within the same product family.
