MPC9992AC Equivalent & Substitute Parts

Part Overview

The MPC9992AC is a Clock Generator, Fanout Distribution, Multiplexer IC manufactured by NXP USA Inc. This device operates at a maximum frequency of 400MHz and is housed in a 32-LQFP package. The part features a Phase-Locked Loop (PLL) with bypass capability, PECL input and output interfaces, and a 2:7 input-to-output ratio configuration. The MPC9992AC is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the MPC9992AC is determined by strict alignment of the following critical parameters:

• Functional Type: Clock Generator, Fanout Distribution, Multiplexer
• Maximum Frequency: 400MHz operation capability
• Input Interface: PECL and Crystal input support
• Output Interface: PECL differential output
• Input:Output Ratio: 2:7 configuration
• Differential Signaling: Both input and output must support differential operation
• PLL with Bypass: Phase-Locked Loop functionality with bypass mode
• Package: 32-LQFP form factor
• Supply Voltage Range: 3.135V ~ 3.465V
• Operating Temperature Range: 0°C ~ 70°C
• Compliance: ROHS3 compliance and MSL 3 rating

Alternative parts must match all of these parameters to ensure functional and electrical compatibility without design modification.

Engineering Selection Recommendations

The MPC9992AC is classified as obsolete. When sourcing this component, the following engineering considerations apply:

Product Status Impact: Obsolete status indicates limited or no ongoing manufacturing. Existing inventory from authorized distributors represents the primary source for procurement.

Compliance Verification: The MPC9992AC maintains ROHS3 compliance and carries an MSL rating of 3 (168 hours), meeting current environmental and moisture handling standards for surface-mount assembly processes.

Supply Chain Considerations: Given the obsolete classification, component availability is finite. Long-term design strategies should evaluate whether functional alternatives from current product lines can satisfy system requirements, though such evaluation falls outside the scope of direct substitution parameters.

Regulatory Status: The part carries REACH Unaffected status and EAR99 ECCN classification, with HTSUS code 8542.39.0001.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the MPC9992AC?

A: A substitute must match all critical parameters: Clock Generator, Fanout Distribution, Multiplexer functionality; 400MHz maximum frequency; PECL input and output interfaces; 2:7 input-to-output ratio; differential input and output capability; PLL with bypass; 32-LQFP package; 3.135V ~ 3.465V supply voltage; 0°C ~ 70°C operating temperature; and ROHS3 compliance with MSL 3 rating.

Q: Why is the MPC9992AC classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production. This classification is assigned by NXP USA Inc. and reflects the product's end-of-life status in the component lifecycle.

Q: Can I use a different package type as a substitute?

A: No. The 32-LQFP package is a critical parameter for PCB layout compatibility. Substitutes must use the identical 32-LQFP (7x7) package specification.

Q: What is the significance of the 2:7 input-to-output ratio?

A: The 2:7 ratio defines the frequency multiplication/division relationship between input and output signals. This ratio is application-specific and must be preserved in any substitute component.

Q: Does the PECL interface requirement limit substitution options?

A: Yes. PECL (Positive Emitter-Coupled Logic) is a specific differential signaling standard. Both input and output must support PECL to maintain signal integrity and compatibility with existing system interfaces.

Q: What does MSL 3 (168 Hours) mean for handling?

A: MSL 3 indicates Moisture Sensitivity Level 3, requiring that the component be used within 168 hours of package opening under controlled humidity conditions. This affects storage, handling, and assembly procedures.

Q: Is the PLL with Bypass feature essential for substitution?

A: Yes. The PLL with bypass capability is a functional requirement. Substitute parts must provide both PLL operation and bypass mode to support different system configurations.
