General Description
Every consumer wants to be free from wires,
but system designers could never find a low-
cost, 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 modules offer a low-touch,
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.
Avnera’s AudioMagic technologies provide
breakthrough wireless audio functionality with
point-to-multipoint transport of uncompressed
stereo PCM audio data from a single
AVMD7300 or AVMD7300 sender and a total
of up to four simultaneous AVMD7300
listeners.
Modules based upon Avnera’s next generation
AudioMagic silicon AV7300 incorporate
enhanced error concealment, low audio jitter,
low latency, reduced power consumption and
digital audio interface for the receiver.

4 Electrical Specifications
4.1 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.
