WSM520V
1. Introduction
The WSM520V module is wireless audio module based on AV5100. The AV5100 is 5GHz wireless audio
SoC (System-on-chip), optimized for building point to multi-point digital wireless audio solutions such as
wireless subwoofers, wireless rear speakers and in home theater system. The AV5100 contains all the
necessary radio transceiver and digital baseband circuitry to form a complete digital wireless node without the
need for external processing.
The WSM520V can be powered from a +5V supply input and the AV5100 contains all the necessary power
management and analog circuitry needed to operate the chip.
The WSM520V can operate in upper bands (5725~5825MHz) of 5GHz spectrum, enabling worldwide
coverage.
