CML Microcircuits has launched its CMX7143 with FFSK/MSK modem functionality. The CMX7143 is a wireless modem product, designed for multi-mode wireless data connectivity, particularly sought-after by Machine-to-Machine (M2M) and Software Defined Radio (SDR) product manufacturers. The product also targets Point-to-Point telemetry systems, traffic location systems and any other wireless data modem applications that require easily configurable multi-mode modem flexibility. The CMX7143 multi-mode wireless data modem is built on CML's proprietary FirmASIC component technology. Initially the product was launched with 4-Level FSK operation, but as the chip is configurable via special Function Image data files to enable further wireless data scheme operation, CML followed its proposed route of additional data scheme support to also include GMSK functionality in addition to 4-Level FSK operation. The roadmap has been further followed, with the addition of the new FFSK/MSK data scheme operation.
The CML's Function Image files configure the on-chip sub-systems of the CMX7143, and are uploaded during device initialisation - the product's function and feature set is then defined. The Function Image can be loaded automatically from an external EEPROM or host microcontroller over the product’s C-BUS serial interface, facilitating in-the-field upgrades if desired. The CMX7143 is available in a small, low power (3.3V with flexible powersave modes), 48-pin VQFN or LQFP package, adding to the growing range of CML products design on FirmASIC technology. An evaluation kit is available (PE0401), facilitating quick and easy design-in.
