Multi-Mode Wireless Data Modem - CMX7143

The NEW CMX7143 addresses the growing global market requirements for multi-mode wireless data connectivity, offering the unique ability to implement different wireless data schemes, with ease, when required.
Wireless data scheme flexibility is a growing market requirement; particularly sought-after by Machine-to-Machine (M2M) and Software Defined Radio (SDR) product manufacturers.

The CMX7143 initially offers 4-Level FSK operation, but the chip is configurable via special Function Image™ data files, enabling the implementation of further wireless data schemes, simply by swapping Function Image™ files. The CMX7143 is supported by a roadmap of future Function Image™ files, the first of which being GMSK operation.

CML's Function Image™ files configure on-chip sub-systems, and are uploaded during device initialisation - the product's function and feature set is then defined.
A Function Image™ can be loaded automatically from an external EEPROM or host microcontroller over the built-in C-BUS serial interface facilitating in-the-field upgrades if desired.

The CMX7143 is targeted at the expanding M2M, and SDR markets, along with Point-to-Point telemetry systems, traffic location systems and any other wireless data modem applications that require easily configurable multi-mode modem flexibility.

Offering a host of features including, 4.8kbps to 19.2kbps data rates, AFSD (Automatic Frame Sync Detection), flexible raw and packet data modes, soft decision decoding, RSSI processing (for Listen Before Transmit Applications) and a C-BUS serial interface to the host microcontroller, the CMX7143 provides everything that is needed in a wireless multi-mode data modem.
Additionally, auxiliary ADCs with multiplex inputs, auxiliary DACs and auxiliary system clocks are provided to aid design and operational flexibility.
The NEW CMX7143 is available in a small, low power (3.0V to 3.6V with flexible powersave modes), 48-pin VQFN or LQFP package. An evaluation kit is available (PE0401), facilitating quick and easy design-in.
