CML Microcircuits CMX7164
Multi-mode Wireless Data Modem

The CMX7164 Multi-mode Wireless Data Modem is a half-duplex device supporting
V.23, GMSK/GFSK, 2-FSK (2-Level FSK), 4-FSK (4-Level FSK), 8-FSK (8-Level FSK), 16-
FSK (16-level FSK), 4 QAM, 16 QAM and 64 QAM operating modes, configurable for
multiple channel spacings via host control.

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 analog 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
minimize host interaction and host I/O resources. Two synthesized 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 utilizes CML’s proprietary FirmASIC® component technology. On-chip subsystems including modulation type, are configured by a Function Image™ (FI) data file that is uploaded during device initialization and defines the device’s function and feature set.

The combination of the CMX7164 Multi-mode Wireless Data modem and the CMX994 Direct Conversion Receiver and CMX998 Cartesian Feedback Loop Transmitter enables the highest integration wireless data modem to be realized. The CMX7164 operates from a 3.0 to 3.6 V supply, includes selectable powersaving modes and is available in small 64-pin VQFN and LQFP packages.
