CMX910L9

Overview

The CMX910L9 is a highly integrated baseband processor IC designed for Automatic Identification System (AIS) applications. It supports three receive channels dedicated to AIS Channel 1, AIS Channel 2, and Digital Selective Calling (DSC), alongside one transmit channel. The device operates on a supply voltage range of 3V to 3.6V and is housed in a 64-LQFP package measuring 10x10 mm.

Feature Summary

• Integrates three distinct receive channels for simultaneous monitoring of AIS traffic and DSC signals
• Includes a dedicated single transmit channel for AIS data transmission
• Provides a complete baseband processing solution for maritime communication protocols

Applications

• Maritime vessel tracking systems
• Shore-based AIS receiver stations
• Integrated bridge navigation systems requiring AIS integration

Procurement Notes

Verify the current lifecycle status as the component is listed as obsolete. Confirm availability through authorized distributors or surplus suppliers. Ensure compatibility with existing system designs due to end-of-life classification. Check for RoHS compliance documentation if required for specific regulatory environments.

Selection Notes

Select this component only for legacy maintenance or specific maritime AIS implementations requiring its exact channel configuration. Evaluate alternative modern baseband processors if designing new equipment, given the obsolete status. Ensure the 64-LQFP footprint matches the PCB layout constraints.

Part Context

This part belongs to the CMX910 family from CML Microcircuits, specialized for VHF digital communications. It serves as a core processing unit for decoding and encoding AIS messages. The L9 suffix typically denotes a specific package variant within the broader CMX910 product line.
