AVNERA CORPORATION | 16505 NW BETHANY COURT SUITE 100 | BEAVERTON, OREGON 97006, U.S.A. | MAIN +1.503.718.4100 | FAX +1.503.718.4101 | WWW.AVNERA.COM AVNERA PROPRIETARY & CONFIDENTIAL | PROVIDED UNDER NDA General Description Every consumer wants to be free from wires, but it has been challenging to find a low-cost, high-quality, easy-to-use wireless audio solution for the wireless subwoofer market. Avnera’s proprietary wireless system takes a new approach to wireless audio. The wireless protocol was designed from the ground up and delivers uncompressed mono or stereo audio, with fixed latency and variable over the air data rate support to eliminate interference problems at the best possible audio quality. 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 certification, antenna tuning and board optimization. Modules based on Avnera’s AV6200 silicon provide breakthrough wireless audio functionality with fixed low-latency point-to- point transport of uncompressed mono PCM audio data at up to 48KHz, 16-bit resolution using digital (I2S) interfaces.

A goal of the design is to have the exact same pin out for both the Tx and Rx modules. The module function is completely determined by firmware. The module pins provide the capability to use either SPI slave or I2C slave interfaces – these are mutually exclusive. If an I2C slave host interface is used GPIOs 2 and 3 can be used for general purpose I/O. In addition, the SPI master port is brought out to the connector to facilitate direct programming of the module flash memory if required. A single I2S port is brought to the connector and can be configured to be either a slave or master port. The MCLK pin can be an input or output to offer optimal flexibility. Likewise the I2S audio pin can be an input or output to implement either audio Tx or Rx. In addition, there are 5 other GPIOs that can be used exclusively for system features such as pair button, interrupt, LEDs etc. The reset pin allows for an external device to reset the module but must be driven from an open drain device to avoid timing issues with the module reset. Note: the connector pin out is subject to change throughout the development process to optimize the PCB routing.
