CMX7141Q3

Overview

The CMX7141Q3 is a digital PMR (DPMR) baseband processor manufactured by CML Micro. It operates on a 3V to 3.6V supply voltage and utilizes a 48-VQFN (7x7) surface-mount package. The component supports DPMR Mode 1, 2, and 3 protocols. It features a power dissipation rating of 1.75 W and is designed for general-purpose RF applications within the CMX7131/CMX7141 series.

Feature Summary

• Supports DPMR Mode 1, 2, and 3 protocol processing
• Integrates baseband functions for digital voice communications
• Designed for low-power wireless device implementation

Applications

• Digital Private Mobile Radio (DPMR) devices
• Professional two-way radio systems
• Secure voice communication terminals

Procurement Notes

Verify the specific suffix Q3 against the manufacturer's latest documentation to confirm pinout compatibility and electrical characteristics. Ensure the design accommodates the 48-VQFN thermal requirements and moisture sensitivity level constraints during assembly. Confirm availability status as distribution channels may report varying stock levels or obsolescence notices.

Selection Notes

Select this component when DPMR Mode 1, 2, or 3 compliance is required for baseband processing. The 48-VQFN package suits space-constrained designs. Compare against the CMX7131L9 if different mode support or package options are needed. Validate that the 3V to 3.6V operating range aligns with the system power architecture.
