CML Microcircuits announced that it has added 16-FSK modulation to the CMX7164 multi-mode wireless data modem portfolio. The addition of 16-FSK constant envelope modulation further enhances the flexibility of this modem IC, enabling telemetry systems to evolve into higher data throughput without the need to move to a linear modulation scenario.

The CMX7164 covers both constant envelope and linear modulation schemes including: GMSK/GFSK, 2/4/8/16-level FSK, 4/16/64 QAM and also provides the ideal platform to support customer-specific modulation schemes. All together these features make the CMX7164 a truly universal Wireless Data Modem solution.

Robust flexible packet data structures including forward error correction and raw data modes are available, supporting user-requirements covering a wide range of applications. An integrated analogue interface supports direct connection to zero IF I/Q radio transceivers with few external components; no external codecs are required.Intelligent auxiliary ADC, DAC and GPIO sub-systems perform valuable functions and minimise host interaction and host I/O resources. Two synthesised system clock generators develop clock signals for off-chip use.

The C-BUS/SPI master interface expands host C-BUS/SPI ports to control external devices. The device utilises CML's proprietary FirmASIC component technology. On-chip sub-systems are configured by a Function Image data file that is uploaded during device initialisation and defines the device's function and feature set.

The CMX7164 is available now, offering low power 3.3V operation in small VQFN/LQFP packaging.
