Wireless Audio core Module is a highly integrated digital core module. By meaning of the Intelligent Wireless technology is developed by Syncomm. It can provide high quality wireless audio for the users. Supporting multiple interfaces such as I2S, USB, embedded RF IC and other key blocks such as I2C control interface, voltage detector. IA2E wireless audio module provides dual transmitter and receiver modes, which enables the seamless transmission of high quality audio. In the transmitter, Tx receives digitized stereo as input, which is packetized and processed for synchronization and data integrity. After that, the data are modulated and radiated at 2.4 GHz ISM band. In the receiver, Rx receives RF signal, demodulated and processed to restore the transmitted signal, and then streamed as digital audio output.
