DWAM80 Digital Wireless
Audio Module
The DWAM80_D2D is an OEM module (42 x 42mm) based on
the STS DARR80. It is an uncompressed wireless digital audio
transceiver operating in the 2.4GHz ISM band. It implements 8
channels with I2S interface or 4 channels with S/PDIF. The
wireless audio link supports up to 4 uncompressed high quality
and low latency stereo audio channels in various network
topologies.
A unique set of protocols and algorithms provides extreme
wireless robustness, capable of dealing with multiple interference
sources as present in the 2.4GHz band. In addition, a wireless
bi-directional data channel is available
The module integrates all functionality for a wireless digital audio
connection, comprising;
- Wireless Audio Processor, DARR 80
- 2.4 GHz radio
- Embedded antennas (Inverted F)
- Dual antenna connector
- Digital audio interfaces
- I2C control interface
- 26 pins interface connector (FFC) for power, digital audio and
control interface and GPIOs
The DWAM80 D2D is used for both Central Unit (CU, transmitter)
and Mobile Unit (MU, receiver). The module is configured either
through the I2C interface, optional EEPROM or microcontroller.
The microcontroller can run application software for more advanced
applications. This yields full application flexibility in terms of data
message transfer, configuration, GPIO management and link control.
