NKR-SWA13Wireless Audio Module

CONFIDENTIAL | PROVIDED UNDER NDA General Description The SWA13-TX module is part of a family of products that represents a new level of system integration offering customers fast time to market with a point-to-point or point-to-multi-point, mono, or stereo, wireless connections. These modules are optimized for low-cost, high-quality and ease-of-use. The SWA13-TX module serves as the sender in point-to-multipoint wireless audio networks. 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 SWA13-TX module integrates all features necessary to complete a wireless stereo or mono link, including AV6301 Wireless Audio Sender 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.

SWA13-TX Functional The SWA13-TX module is available in a single incarnation; digital input transmitter module. There are two I2S ports, a separate I2S port for digital audio input and an I2S out port is available for future applications. I2S may be configured to be a master or a slave. In addition, MCLK can be generated from the module, or input to the module as required by the system application. 錯誤! 找不到參照來源。 shows the block diagram of the SWA13-TX module. The highly integrated nature of the AV6301 transceiver IC results in few external components being required for the SWA13 module design. 2 PCB antennas are used to achieve increased range through antenna diversity. The simple RF path consists only of the antennas, associated tuning components, an RF switch and a balun connected to the AV6301 IC. A 16MHz crystal generates the AV6301 system clock signal used as the basis for all RF and digital audio signals. A 2Mb flash memory stores the factory based firmware, as well as firmware upgrade images and configuration parameters. The module firmware enables upgrades to be performed by the I2C slave interface or over-the-air. The module can be controlled from an external host device via the I2C interface. The I2C master port allows the module to control other system devices such without having to add another MCU to the product design. Up to a maximum of 17 GPIOs are supported with the SWA13 module including I2C and I2S signals. This large number of GPIOs can be leveraged to implement low cost sub-woofer designs as outlined below. The SWA13-TX module offers both standard latency and low-latency firmware with different over the air sample rate. While the standard 22.2KSps over the air sample rate optimizes audio quality and WiFi co-existence performance; Lower audio latency can be achieved by using the low-latency 44.4KSps over the air sample rate.

SWA13-TX Module Connections 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. I2S In Port The I2S input port can be configured as a master or slave. Consequently BCLK and WCLK can be either inputs or outputs. In addition, MCLK can be generated by the module on pin 16, or used as an input. Typically, as the AV6301 IC contains a sample rate converter, MCLK is not required to be supplied to the module when it is an I2S slave. CMOS 3.3 logic levels are used for all I2S signals. I2C Slave Port The I2C slave port is used for external host communication and during module test. It is assumed that external pull up resistors are connected at the I2C master communicating with the module. I2C Master Port The I2C master port is used to communicate with external audio devices such as a sub-woofer amplifier. The SDA and SCL signal lines have pull ups internal to the module. GPIOs 3.3V CMOS logic level GPIOs available to connect to other devices, or to use as UI supporting GPIOs for LED and button support. All supported GPIOs can be configured as inputs or outputs.
