Product Preview PP/7146/1 August 2019 CMX7146BPSK Wireless Data ModulatorThe CMX7146 is a flexible data transmitter supporting BPSK (Binary Phase Shift Keying) and Differential BPSK modulation (sometimes called PRK, Phase Reversal Keying or 2PSK). BPSK is often used when robust, long-range data communication is required. It is also simple to demodulate and power efficient. Functional Summary • Data rates supported 600/1200/2400/3600/4800/9600bps • Up to 13 bytes per burst • PA ramp DAC • Baseband IQ outputs forRF modulation • Additional data converters • C-BUS (SPI compatible) serial control interface The CMX7146 generates precise baseband analogue in-phase and quadrature signals, which allow the transmitted signal to be generated with high accuracy, making it suitable for up-conversion to an RF carrier of the user's choice. The device supports raw (bits in, modulation data out) and preloaded (messages in, modulation data out) transmissions and also features a transmit (Tx) trigger input to enable precisely timed data transfers. A power amplifier ramping DAC can also be employed to control transmission bursts which can be synchronised as part of the transmit sequence. Technical features • Plain or differential BPSK • Programmable RRC filter In addition to the modulation function, when used in sensor interfacing solutions, the CMX7146 integrates low power analogue to digital converters, featuring programmable thresholds and 4 GPIO interfaces. • a=0.2/0.3/0.35 Low power consumption • 7mA TX 1200bps • 15mA 9600bps Flexible clocking options Through port control for IQ up-converter Auxiliary converters for sensor interfacing 3.3V supply Small 48QFN package (Q3) Operating from a 3.3V supply, the CMX7146 is designed using CML's FirmASIC* technology. A Function Image™ (FI) file, which defines the operational capabilities of the device, is available from the CML Technical Portal. The Function Image™ is uploaded from either the host controller or external memory into the device during the power-up sequence .
