CMX7143L4-TR1K

Overview

The CMX7143L4-TR1K is a multi-mode wireless data modem IC manufactured by CML Micro, designed for half-duplex communication applications. It operates on a single 3.3V supply and supports flexible bit rates ranging from 2k to 20kbps. The device utilizes Function Image technology to enable 4FSK modulation with over-air compatibility for RD-LAP Tx/Rx. It features automatic frame sync detection, preamble insertion, and carrier sense capabilities. The component is housed in a 48-pin LQFP package (suffix L4) and is supplied in tape and reel packaging (suffix TR1K).

Feature Summary

Supports 4FSK modulation with automatic frame sync detection and preamble insertion.
Includes two auxiliary ADCs and four auxiliary DACs, with one DAC featuring RAMDAC capability for PA ramping.
Features carrier sense functionality for listen-before-talk operation and flexible power save modes.
Connects to host microcontrollers via an optimized C-BUS serial interface.

Applications

Wireless data modems requiring half-duplex communication.
RD-LAP compatible transceiver systems.
Low-power IoT sensor networks.

Procurement Notes

Verify the specific ordering suffixes against manufacturer documentation to ensure correct package and reel configuration. Confirm that the Function Image version aligns with the required modulation type. Check for RoHS compliance status and moisture sensitivity levels prior to assembly planning.

Selection Notes

Select this model when 4FSK modulation is required for RD-LAP compatibility. Ensure the design accommodates the 48-pin LQFP footprint. Verify that the host system can support the C-BUS interface protocol and that the 3.3V power rail meets the current requirements for the intended application.

Part Context

This component belongs to the CMX7143 series of multi-mode wireless data modems. The L4 suffix indicates the 48-pin LQFP package variant, while TR1K denotes the tape and reel packaging format containing 1,000 units per reel. Other variants exist with different packages or Function Images supporting GMSK or FFSK/MSK.
