CONFIDENTIAL | PROVIDED UNDER NDA

General Description

The SWA16 module family of products

represents 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

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 industry leading coexistence with WiFi –

even at close proximity to a WiFi device.

The SWA16 module integrates all features

necessary to complete a wireless stereo ro

mono link, including AV6100 Wireless Audio

Chip, printed diversity antenna, flash memory,

interface connector and all passive

components. Just supply 5 Volts and an I2S

interface and you are ready to create a

wireless audio link.

The module measures just 26 x 60 x 3.5 mm

and is provided with a 24 pin FPC connector

or pin header for connection to the system

board.

The module is certified to FCC and CE

standards.

SWA16 Module Datasheet 1 Rev 1.0 SWA16 Functional be achieved by using the low-latency 44.4KSps over the air sample rate. The SWA16 module is available in 2 variations; digital input transmitter module or digital output receiver module. There is a separate I2S port for digital audio input and output functions and either of these can be configured to be a master or a slave – only the input or output port can be active at any time.

SWA16 Module Datasheet Rev 1.0 SWA16 Module Connections 1.2 Signal Type Description +5V Supply Single +5V +/10% supply rail to the module Reset Active low reset input. This pin is driven from an open collector/drain device such that it can pull to ground for the active reset state but, when released, must go to a high impedance state. If this input is driven high the internal reset circuit on the module will not operate correctly.

SWA16 Module Datasheet 3 Rev 1.0 Electrical Specifications 3.1 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 failure (destructive breakdown). Stresses beyond those listed under AMR may cause permanent damage to the device.

SWA16 Module Datasheet 3.5 Rev 1.0 I2C Master/Slave Communication Interface Timing (S_SCL, S_SDA) The SWA16 has both I2C slave and master interfaces available with their respective pins S_SCL and S_SDA. The interfaces operate in I2C fast-mode and can receive and transmit at up to 400 kbit/s. Bytes are 8 bits long and are transferred with the most significant bit (MSB) first. Each byte has to be followed by an acknowledge bit.
