MPC9350AC

Overview

The MPC9350AC is a low voltage PLL clock driver manufactured by NXP USA Inc. (formerly Freescale Semiconductor). It operates within a supply voltage range of 2.5 V to 3.3 V and supports output frequencies up to 200 MHz. The device features nine LVCMOS outputs with maximum output-to-output skew of 150 ps. It includes an internal fully differential PLL, configurable divide-by-2, 4, and 8 output dividers, and selectable feedback ratios of ÷16 or ÷32. The component is housed in a 32-lead LQFP package and functions across an extended temperature range of -40 °C to +85 °C.

Feature Summary

• Nine LVCMOS clock outputs with maximum 150 ps output-to-output skew
• Internal fully differential PLL supporting 200–400 MHz VCO frequency
• Configurable output division ratios (÷2, ÷4, ÷8) via FSEL pins
• Selectable input reference sources: crystal oscillator or LVCMOS TCLK

Applications

• High-performance clock distribution systems for microprocessors
• Networking equipment requiring precise clock synchronization
• Telecommunications infrastructure applications
• Computer systems utilizing PowerQUICC II integrated communication microprocessors

Procurement Notes

Verify the AC suffix indicates the standard operating temperature range of -40 °C to +85 °C. Confirm the package type is the 32-lead LQFP (Case 873A-03). Check current availability status as this component originates from legacy Freescale Semiconductor documentation dated 2005.

Selection Notes

Select the MPC9350AC when designing systems requiring up to nine clock outputs with low skew characteristics. Ensure the design accommodates the 2.5 V or 3.3 V supply requirements. Verify that the required output frequencies fall within the 25 MHz to 200 MHz range supported by the internal VCO and divider configurations.

Part Context

The MPC9350AC belongs to the Advanced Clock Drivers Devices family produced by Freescale Semiconductor, now part of NXP USA Inc. This series targets high-performance clock tree designs for demanding environments such as telecommunications and networking. The AC suffix specifically denotes the extended industrial temperature range variant.

Replacement Considerations

Consult the MPC9351 data sheet for alternative input-to-output relationships in external feedback mode. Verify compatibility with specific microprocessor clocking needs, particularly those involving PowerQUICC II architectures.
