CMX7146

– BPSK Wireless Data Modulator

The 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.

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.

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.

Devices are available through our Distributor Network.
