8.4.1 OOK Mode

Data at the D input is modulated with the carrier frequency set by the RF_SET value when the device is transmitting (MODE = VCC). See Section 8.3.1 section for more details. In receiving (MODE = GND), the device expects an OOK modulated signal at the A and B inputs. The data is demodulated and sent out via R pin. See Section 8.3.2 section for more details.
