MPC9772FAR2

Overview

The MPC9772FAR2 is a 3.3V LVCMOS PLL clock generator manufactured by NXP USA Inc., packaged in a 52-lead LQFP (CASE 848D). It provides up to 12 outputs with frequencies reaching 240 MHz and output skew under 250 ps. The device supports an input-to-output ratio of 3:12, operates on a 3.135V to 3.465V supply, and functions within -40°C to +85°C. It features internal power-on reset, zero-delay buffer capability via external feedback, and individual synchronous output stop circuitry for power management.

Feature Summary

• Generates clock signals up to 240 MHz with maximum output skew of 250 ps
• Supports zero-delay buffer configuration through external PLL feedback path
• Includes individual synchronous output stop circuitry for power down support
• Features internal crystal oscillator or two LVCMOS reference clock inputs

Applications

• High-performance networking equipment clock distribution
• Computing system timing solutions
• Telecom infrastructure applications

Procurement Notes

Verify component authenticity as the MPC9772FAR2 is listed as obsolete by distributors. Confirm RoHS compliance status, as sources indicate non-compliance. Ensure the 52-LQFP package matches design requirements and check for available replacement components from NXP or alternative manufacturers if production continuity is required.

Selection Notes

Select this component when low-skew LVCMOS clock distribution is needed for mid-range to high-performance systems. Ensure the design accommodates the 3.3V supply voltage and 52-lead LQFP footprint. Verify that the required output frequencies fall within the 240 MHz limit and that the application can utilize the serial clock stop interface for power management.

Part Context

The MPC9772 belongs to the MPC97 family of clock generators. It is pin and function compatible with the MPC972. Originally developed by Motorola Semiconductor, the product line was later managed by Freescale Semiconductor and subsequently NXP USA Inc. The device is designed for applications requiring precise timing and multiple clock outputs from a single reference.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the MPC9772FAR2 is marked as obsolete, engineers should consult NXP official resources for direct replacements or evaluate the pin-compatible MPC972 if functional requirements allow.
