MPC9330AC

Overview

The MPC9330AC is a 3.3 V LVCMOS PLL clock generator manufactured by NXP USA Inc., formerly Freescale Semiconductor. It provides low-skew clock distribution for telecommunication, networking, and computing applications. The device features an internal crystal oscillator or alternative LVCMOS reference input, generating output frequencies up to 120 MHz with maximum output skew of 150 ps. It supports zero-delay operation in external feedback mode and includes synchronous output clock stop functionality. The component operates within a temperature range of 0°C to +70°C and is housed in a 32-lead LQFP package.

Feature Summary

• Generates clock signals up to 120 MHz with maximum output skew of 150 ps
• Supports zero-delay operation via external PLL feedback configuration
• Includes on-chip crystal oscillator and alternative LVCMOS reference clock input
• Features synchronous output clock stop in logic low state to eliminate runt pulses

Applications

• High-performance telecommunication systems
• Networking equipment requiring precise clock distribution
• Computing applications demanding low-skew clock signals

Procurement Notes

Verify the specific suffix AC indicates a Pb-free package variant as per the datasheet. Confirm that the part status is End-of-Life (EOL) before procurement planning. Ensure compatibility with 3.3 V power supply requirements and check for availability through authorized distributors given the discontinued status.

Selection Notes

Select this component when designing systems requiring a 1:6 LVCMOS PLL clock generator with outputs up to 120 MHz. Ensure the application environment stays within the specified 0°C to +70°C operating temperature range. Verify that the system can accommodate the 32-lead LQFP packaging and provide appropriate filtering for the VCC_PLL pin to minimize jitter.

Part Context

The MPC9330AC belongs to the MPC93 family of advanced clock drivers from NXP/Freescale. It is functionally compatible with the MPC930 but offers enhanced features such as zero-delay buffer capability and synchronous clock stop. The AC suffix specifically denotes the lead-free package version within the 32-lead LQFP form factor.

Replacement Considerations

The datasheet notes pin and function compatibility with the MPC930. Designers should verify if the MPC930 meets all performance requirements, particularly regarding zero-delay operation and output skew specifications, as a potential replacement.
