CMX7341Q3

Overview

The CMX7341Q3 is a PMR/LMR Common Platform Processor designed for digital radio baseband processing. It supports DMR, dPMR, NXDN, ARIB-STD-T98-T102, APCO-25, and analogue standards. The device operates on a supply voltage range of 3 V to 3.6 V with a maximum input frequency of 24.576 MHz and a typical operating frequency of 19.2 MHz. It functions within a temperature range of -40°C to +85°C and is housed in a 48-VQFN (7x7 mm) surface-mount package.

Feature Summary

• Supports multiple digital radio protocols including DMR, dPMR, NXDN, and APCO-25
• Integrated baseband processor for PMR and LMR applications
• Capable of handling both digital and analogue modulation schemes

Applications

• DMR digital radio systems
• dPMR portable and mobile radios
• NXDN communication devices
• APCO-25 public safety radios
• Analogue two-way radio transceivers

Procurement Notes

Verify the specific suffix (Q3) against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 48-VQFN footprint aligns with your PCB layout guidelines. Confirm RoHS compliance status through the current component certificate provided by CML Microcircuits prior to final procurement.

Selection Notes

Select this component when a unified baseband solution is required for multi-standard PMR/LMR radios. It integrates processing for various digital modes alongside analogue support, reducing bill-of-materials complexity. Consider the 48-VQFN package size and thermal dissipation capabilities (1.75 W) during mechanical design. Verify that the 3V to 3.6V supply range matches your system power architecture.

Part Context

The CMX7341Q3 belongs to the CMX7241/CMX7341 series from CML Microcircuits. This family targets the Professional Mobile Radio (PMR) and Land Mobile Radio (LMR) markets. The Q3 variant specifically denotes the commercial temperature grade and packaging configuration. It serves as a core processing unit for modern hybrid radio infrastructure.

Replacement Considerations

Consult the official CML Micro cross-reference guide for verified substitutes. No direct public substitute part numbers are confirmed in available documentation. Evaluate functional compatibility if considering alternative vendors.
