Flexible Multi-Mode Wireless Data Modem Targets M2M and SDR Markets
CML Microcircuits has launched the CMX7143, a highly integrated and adaptable multi-mode wireless data modem built on CML’s proprietary FirmASIC® component technology. The 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. The device 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 initialization 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.
