The Module is an OEM module (35x35mm) based on the SMSC DARR83. It is an uncompressed wireless digital
audio transceiver operating in the 2.4GHz, 5.2GHz and 5.8GHz bands. The wireless audio link supports up to 4
stereo audio streams and comes together with additional features such as: data encryption, pairing functionality, bi-
directional control data messages, low power audio snooze mode, WLAN detection and Automatic Frequency
Allocation. The DARR83 chip itself provides the basic functions of Audio Processing and buffering, Data Link
Layer and Physical Layer. The module integrates all functionality for a wireless digital audio connection,
comprising:
x DARR83 Wireless Audio Processor
x 2.4GHz/ 5.2GHz/ 5.8 GHz RF Transceiver
x Embedded Antennas
x Digital audio interfaces (I2S and/or S/PDIF)
x I
2C control interface
x 26 pins interface connector (FFC) for power, digital audio and control interface and GPIOs
x Built-in 1MB SPI interface Flash 3V 4KB uniform sector

IMPORTANT NOTE
This device complies with FCC & IC radiation exposure limits set forth for an uncontrolled environment. This device should be installed and
operated with minimum distance 20cm between the radiating element of this device and the user. This device must not be co-located or
operating in conjunction with any other antenna or transmitter.
This device is intended only for OEM integrators and following statements shall be included to host user manual
1) The antenna must be installed such that 20cm is maintained between the antenna and users.
2) This module may not be co-located with any other transmitters or antennas.
As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for
testing their end-product for any additional compliance requirements with this module installed.
In the event that these conditions cannot be met, then the FCC & IC authorizations are no longer considered valid and the FCC ID cannot
be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product including this
module and obtaining separate FCC & IC authorizations.
This module has been designed for indoor used only. Therefore the end-product with this module installed is permitted to use
indoors only.
NOTE IMPORTANTE
Cet appareil est conforme aux limites de la FCC et IC exposition aux radiations dans un environnement non contrôlé. Cet appareil doit être
