MPC9230FN Equivalent & Substitute Parts

Part Overview

The MPC9230FN is a Clock/Frequency Synthesizer and Clock Generator Multiplexer IC manufactured by NXP USA Inc., designed for 750MHz operation in a 28-LCC (J-Lead) surface mount package. This device features an integrated Phase-Locked Loop (PLL) with bypass capability, crystal input, and LVPECL output configuration. The MPC9230FN is classified as obsolete, making identification of functionally equivalent substitute components necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPC9230FN are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Clock/Timing category classification
• Maximum frequency capability (≥750 MHz or compatible operating range)
• LVPECL output signal type
• Surface mount packaging with compatible pinout
• Operating temperature range (-40°C ~ 85°C)
• Supply voltage compatibility (3.0V ~ 3.6V range)

Substitute Parts Identified:

1. MPC9230AC (NXP USA Inc.) - Same-family alternative with identical electrical specifications but different package format (32-LQFP vs. 28-LCC). Maintains 750 MHz maximum frequency, crystal input, LVPECL output, and 1:1 input:output ratio. Offers improved RoHS3 compliance status.

2. CDCVF111FN (Texas Instruments) - Cross-manufacturer alternative functioning as a Clock Fanout Buffer (Distribution) IC. Operates at 650 MHz maximum frequency with 1:9 input:output ratio, LVPECL input/output, and compatible supply voltage range (3.0V ~ 3.6V). Provides superior RoHS3 compliance and MSL rating (1 vs. 2).

Parameter Comparison

Engineering Selection Recommendations

MPC9230AC Selection Criteria: The MPC9230AC represents the closest functional equivalent to the MPC9230FN, maintaining identical electrical specifications (750 MHz maximum frequency, 1:1 input:output ratio, crystal input, LVPECL output, and matching supply voltage range). Both devices are NXP USA Inc. products within the same base product family (MPC92). The primary difference is package format (32-LQFP vs. 28-LCC). Selection of MPC9230AC is appropriate when PCB layout can accommodate the 32-LQFP package footprint and when RoHS3 compliance is required. Both parts remain classified as obsolete.

CDCVF111FN Selection Criteria: The CDCVF111FN from Texas Instruments offers the advantage of active product status and superior compliance certifications (ROHS3 Compliant, MSL 1 with unlimited shelf life). This device functions as a clock distribution buffer rather than a synthesizer, operating at 650 MHz maximum frequency with 1:9 fanout capability. Selection of CDCVF111FN is appropriate for applications requiring clock distribution to multiple endpoints, active product availability, and enhanced environmental compliance. The 28-LCC (J-Lead) package maintains footprint compatibility with the original MPC9230FN.

Frequently Asked Questions (FAQ)

Q: Can MPC9230AC directly replace MPC9230FN in existing designs? A: MPC9230AC maintains identical electrical specifications and supply voltage requirements. Direct replacement is feasible if the PCB layout can accommodate the 32-LQFP package (7x7mm) in place of the 28-LCC (J-Lead) package (11.51x11.51mm). Pin configuration differences require schematic and layout verification.

Q: What is the functional difference between MPC9230FN and CDCVF111FN? A: MPC9230FN is a clock synthesizer with 1:1 input:output ratio, while CDCVF111FN is a fanout buffer with 1:9 distribution capability. CDCVF111FN operates at 650 MHz maximum versus 750 MHz for MPC9230FN. Both provide LVPECL output and compatible supply voltage ranges.

Q: Why is CDCVF111FN listed as active while MPC9230FN is obsolete? A: Product status reflects current manufacturer availability and support. CDCVF111FN (Texas Instruments) maintains active production status, while MPC9230FN (NXP USA Inc.) has been discontinued. For new designs requiring long-term component availability, CDCVF111FN provides superior supply chain assurance.

Q: Are there package compatibility considerations between these parts? A: Yes. MPC9230FN uses 28-LCC (J-Lead) packaging, MPC9230AC uses 32-LQFP, and CDCVF111FN uses 28-LCC (J-Lead). MPC9230FN and CDCVF111FN share identical package format but different pinouts. MPC9230AC requires different PCB footprint design.

Q: What compliance advantages do the substitute parts offer? A: Both MPC9230AC and CDCVF111FN are ROHS3 compliant, compared to the RoHS non-compliant status of MPC9230FN. CDCVF111FN provides superior moisture sensitivity rating (MSL 1 with unlimited shelf life vs. MSL 2 with 1-year limit for MPC9230FN).

Q: Is frequency derating necessary when substituting with CDCVF111FN? A: CDCVF111FN operates at 650 MHz maximum versus 750 MHz for MPC9230FN. Applications requiring operation above 650 MHz cannot use CDCVF111FN. Applications operating below 650 MHz are compatible.
