Preliminary Module Brief

Point-to-point AVMD6210-SWA12TX/RX modules for Stereo and Mono

Wireless Audio Systems, based on Avnera’s AV6210 IC

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-to­point transport of uncompressed mono PCM
audio data at up to 48KHz, 16-bit resolution
using digital (I2S) interfaces.

4 AVMD6210-SWA12- Connector Information

Table 1 shows the module connector pin out for the SWA12. A goal of the design is to have the e xact same pin out for
both the Tx and Rx modules. The module function is completely determined by firmware.

The module pins provide the capabilit y to use e ither SPI sl av e or I2C slav e interfac es – th ese are mutua ll y exclusiv e. 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 programmin g 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 excl usively for s ystem features su ch as pair button, i nterrupt, LEDs
etc. The reset pin allows for an external device to reset the module but m ust be driven from an open dra in 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.

6 Electrical Specifications

6.1 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 fail ure (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 sp ecifications are given under Electrical Char acteristics at
the test conditions specified.
