CONFIDENTIAL | PROVIDED UNDER NDA

General Description

The SWA52 module is a member of a family of

products representing a new level of system

integration offering customers fast time to

market with a point-to-point mono, or stereo,

wireless connection. These modules are

optimized for low-cost, high-quality and ease-

of-use.

The module incorporates Avnera’s proprietary

5GHz wireless audio protocol, designed from

the ground up specifically for audio. It features

low fixed latency, uncompressed CD quality

mono or stereo audio, superior interference

immunity, and inherent coexistence with WiFi.

Extended range is enabled on SWA52 with an

external RF power amplifier (PA), increasing

typical transmit power to as much as 12dBm

typical.

The SWA52 module integrates all features

necessary to complete a wireless stereo or

mono link, including AV5100 Wireless Audio

Chip, printed diversity antennas, PA, shield

can, flash memory, interface connector and all

passive components. Just provide power and

an I2S interface and you are ready to create a

wireless audio link.

The module measures 35 x 35 x 3.5 mm and

is provided with a 24 pin FPC connector.

The module is certified to FCC and CE

standards.

SWA52 Module Datasheet Rev 1.3 4 SWA52 Functional Description The SWA52 module is available in 2 variations; digital input transmitter module or digital output receiver module. There are three available I2S digital audio data inputs/outputs, each of these can be configured to operate as either a master or a slave - depending on the application, the I2S ports can operate simultaneously as either inputs or outputs.

SWA52 Module Datasheet 4.1 Rev 1.3 Typical Sub-Woofer Implementation A basic AV5100 Wireless Subwoofer system block Diagram is shown in below Figure 1: AV5100 Wireless Subwoofer Solution Block Diagram A simple low cost implementation of sub-woofer design is shown in Figure 3. The sub amplifier consists of a PWM chip plus an output stage device, but no external MCU is required as the SWA52-RX module performs the control function using the I2C master communication port in conjunction with multiple GPIOs.

SWA52 Module Datasheet 4.2 Rev 1.3 SWA52 Module Connections and Interfaces Signal Type Description +5.0V Supply The SWA52 hardware is configured to accept a nominal +5.0V supply. Reset Active low reset input. This pin is driven from an open collector/drain device such that it can be pulled to ground for the active reset state but, when released, must go to a high impedance state. This pin should not be actively driven high, as the AV5100 internal reset circuit will not operate correctly.
