CMX7341Q3-TR1K

Overview

The CMX7341Q3-TR1K is a PMR/LMR Common Platform Processor by CML Microcircuits, designed for marine and professional radio solutions. It operates within a frequency range of 3 MHz to 24.576 MHz, with a typical operating frequency of 19.2 MHz. The device supports supply voltages between 3 V and 3.6 V, dissipating up to 1.75 W of power. It is housed in a 48-VQFN (7x7 mm) surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports multiple digital protocols including DMR, dPMR, NXDN, ARIB-STD-T98-T102, APCO-25, and analogue standards
• Provides a common platform architecture for versatile marine and land mobile radio applications
• Integrates baseband processing capabilities for efficient signal handling

Applications

• Marine radio communication systems
• DMR and dPMR handheld or mobile radios
• NXDN and APCO-25 professional radio infrastructure
• Analogue two-way radio transceivers

Procurement Notes

Verify the specific suffix 'TR1K' indicates tape-and-reel packaging rather than tray packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 48-VQFN footprint matches the target PCB design constraints. Validate that the 3V to 3.6V supply range aligns with the system power architecture.

Selection Notes

Select this component for designs requiring a unified processor for diverse PMR/LMR standards. The 48-VQFN package suits space-constrained surface-mount applications. Consider the 1.75W power dissipation for thermal management planning. The wide input frequency range allows flexibility in local oscillator design. Verify compatibility with required protocol stacks before finalizing the bill of materials.

Part Context

The CMX7341 series serves as a core processor for CML Micro's marine and professional radio portfolio. This model specifically targets the intersection of digital and analogue radio technologies. It enables manufacturers to develop multi-standard devices using a single silicon platform. The Q3 variant denotes specific packaging and reel configuration options within the broader family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The CMX7341Q3 is the primary tray-packaged equivalent. Designers should consult CML Microcircuits directly for qualified alternatives or updated revisions.
