CMX7042Q3

Overview

The CMX7042Q3 is a marine Automatic Identification System (AIS) baseband processor designed for limiter-discriminator based RF systems. It operates on a 3V to 3.6V supply and utilizes a 48-VQFN (7x7) surface-mount package. The component supports AIS Class-A and Class-B protocols, as well as exacTrax functionality. Built on silicon technology, it is rated for an operating temperature range of -40°C to +85°C and features moisture sensitivity level 3.

Feature Summary

• Supports Marine AIS Class-A and Class-B data processing
• Enables exacTrax tracking capabilities
• Compatible with limiter-discriminator RF architectures

Applications

• Marine vessel communication equipment
• AIS transponder systems
• Maritime navigation and tracking devices

Procurement Notes

Verify the specific suffix Q3 against official CML Micro documentation to confirm the exact tape-and-reel packaging configuration and pinout compatibility. Ensure that the selected variant matches the required board space and thermal dissipation characteristics for the target application design.

Selection Notes

Select this component when designing marine AIS receivers or transponders requiring integrated baseband processing for Class-A, Class-B, and exacTrax standards. It is suitable for applications utilizing limiter-discriminator front-ends rather than direct sampling architectures.

Part Context

This part belongs to the CMX7042 series of marine AIS baseband processors from CML Microcircuits. It serves as a specialized solution for maritime data handling, complementing other models like the CMX7032 which includes integrated RF synthesizers.

Replacement Considerations

The CMX7042L4 is a documented alternative within the same product family, offering similar AIS baseband processing capabilities in a different package format.
