Wifi Revolution

CML Microcircuits, a provider of low power semiconductors for global wireless and telecom markets, has launched a new multi-mode wireless data modem that offers the unique ability to implement different wireless data schemes, with ease, when required.

The new CMX7143 is an integrated and adaptable multi-mode wireless data modem built on the company’s FirmASIC component technology offering a host of benefits and capabilities 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 micro controller. Also, auxiliary ADCs with multiplex inputs, auxiliary DACs and auxiliary system clocks are provided to aid design and operational flexibility.

Moreover, CMX7143 is available in a small, low power (3.0V to 3.6V with flexible power save modes), 48-pin VQFN or LQFP package.

The CMX7143 is targeted at the expanding Machine-to-Machine (M2M) and Software Defined Radio (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.

The CMX7143, which is supported by a roadmap of future function image files, the first of which being GMSK operation, initially offers 4-level FSK operation.

The chip however is configurable via special function image data files, enabling the implementation of further wireless data schemes, simply by swapping function image files.

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.

The function image can be loaded automatically from an external EEPROM or from a host micro controller over the built-in C-BUS serial interface, facilitating in-the-field upgrades if desired.
