SKY76303-21

High-Resolution Wireless Audio System-on-Chip (SoC)

The SKY76303-21 High-Resolution Wireless Audio SoC is optimized for building point-to-multi-point digital wireless audio solutions (such as wireless subwoofers and wireless rear speakers for in-home theater systems), and wireless gaming headsets and wireless microphones.

The SKY76303-21 leverages the proven Skyworks proprietary RF protocol, providing the same excellent coexistence performance found in the AV62xx/63xx wireless SoC product family. The SKY76303-21 SoC also expands the capabilities of world-class wireless audio protocol by providing increased audio resolution, digital I/O and over-the-air (OTA) signal routing flexibility to accommodate a wide range of wireless audio applications.

The SKY76303-21 contains all the necessary radio transceiver and digital baseband circuitry to form a complete digital wireless node without external processing. The SKY76303-21 can operate in the lower and upper bands of the 5 GHz spectrum, enabling worldwide coverage.

The SKY76303-21 contains all the necessary power management and analog circuitry needed to operate the chip. The chip is powered from either a +5 V supply input (powering the internal +3.3 V output LDO) or an externally regulated 3.3 V supply.

The SKY76303-21 also contains a set of General- Purpose Inputs/Outputs (GPIOs) for various control and interface functions.

In various module and product implementations, the SKY76303-21 RF section and wireless protocol has been certified globally, including North America, Europe, China, Japan, and Korea.
