General Description
Every consumer wants to be free from wires,
but system designers could never find a lowcost, high-quality, easy-to-use wireless audio
solution for speakers, microphones,
headphones and headsets on the market.
Avnera’s proprietary wireless system changes
the game by taking a new approach to
wireless audio. The wireless protocol was
designed from the ground up and delivers
uncompressed stereo audio over the air
without interference problems.
Avnera’s wireless USB dongle offers a lowtouch, easy-to-integrate wireless audio
solution and enable fast time to market by
already solving the problem associated with
FCC, antenna tuning and board optimization.
The AVRB7201-05 USB dongle provides
breakthrough wireless audio functionality with
point to point transport of uncompressed
stereo PCM audio data from an AVRB7201-05
sender to an AVMD72x2 listener.

Absolute Maximum Ratings
Absolute Maximum Ratings (AMR) are stress ratings only. AMR corresponds to the maximum value that can be applied without leading
to instantaneous or very short-term unrecoverable hard failure (destructive breakdown). Stresses beyond those listed under AMR may
cause permanent damage to the device.
Functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Range” is
not implied. Exposure to absolute-maximum-rated conditions for extended periods may adversely affect device reliability.
Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test
conditions specified.
