CMX7041L4

Overview

The CMX7041L4 is a half-duplex TWR processor from CML Microcircuits, designed for voice signalling and data functions. It operates on a supply voltage range of 3 V to 3.6 V and supports an input frequency between 9.6 MHz and 19.2 MHz. The device is housed in a 48-LQFP (7x7) surface-mount package with a maximum power dissipation of 1.6 W. It functions within a temperature range of -40°C to +85°C and utilizes silicon technology.

Feature Summary

• Supports half-duplex Time Word Resolution processing
• Integrates voice signalling and data function capabilities
• Includes built-in AIS Class-A/B and exacTrax enabling

Applications

• Maritime AIS transponder systems
• Vessel tracking and identification networks
• Marine communication base stations

Procurement Notes

Verify the specific suffix L4 against official CML Micro documentation to confirm pinout and electrical characteristics. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the 48-LQFP package matches the target PCB footprint requirements. Check for moisture sensitivity level handling instructions during storage and assembly.

Selection Notes

Select this component when half-duplex TWR processing with integrated voice and data signalling is required. Compare against the CMX7042L4 if full-duplex operation or different modulation schemes are needed. Verify that the 3V to 3.6V supply range aligns with the system power architecture. Consider the 48-LQFP package constraints for layout design.

Part Context

This part belongs to the CMX7031/CMX7041 series of RF wireless miscellaneous ICs. It complements other CML Micro solutions like the CMX7042L4, which offers similar processing but potentially different duplexing modes. The series targets specialized maritime and wireless communication applications requiring robust signal processing.
