NKR-SWA54Wireless Audio Module

Different label color and WNC P/Ns are used to distinguish between TX and RX. General Description The SWA54 module is a member of the VMX family of wireless module products. The VMX module product concept offers customers fast time to market for point-to -multipoint mono, stereo, or multichannel wireless audio connection. It incorporates Skyworks newest wireless audio chip, Sky76303-21. As the successor to SKY76303-21, the SKY76303-21 adds high resolution audio to Skyworks world-class proprietary radio protocol as well as an improved RF interface, containing upgrades to 5 GHz band coverage and user flexibility as well as upgraded interference immunity. The radio retains the core features and functions of its predecessors including low and fixed latency audio, superior interference immunity, and inherent coexistence with WiFi. The SWA54 module hardware integrates all components necessary to complete a 5 GHz wireless multi-client, multichannel link, including SKY76303-21 Wireless Audio Chip, printed diversity antennas, 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 designed to pass FCC, CE, and IC along with various other regional standards.

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. When configured as slaves, the I2S inputs/outputs can be independently clocked by up to two external masters. In addition, MCLK can be output from the module to provide a reference clock source to an external ADC or DAC. MCLK can also be input to the module to provide a reference clock from an external source. Figure 1 shows the block diagram of the SWA54 module. The hardware for the audio input (transmit) and audio output (receive) versions of the module is identical and only the firmware loaded onto the module determines its function. The highly integrated nature of the SKY76303-21 transceiver IC results in few external components being required for the SWA54 module design. 2 printed PCB antennas are used to achieve increased range, and to achieve antenna spatial diversity. The extended-range RF path consists of the antennas, associated tuning components, shield can, the RF switch, RF power amplifer (PA) and two baluns, one connected to each of the RF input/output ports on the SKY76303-21 IC. A 16MHz crystal oscillator generates the SKY76303-21 fundamental system clock used as the basis for all RF and digital audio clocks. A 2Mb flash memory chip is used to store the module’s application firmware. The SKY76303-21 is able to boot from internal ROM upon first power up, which enables programming the flash chip with the application firmware through USB. In addition, Over-the-air Firmware upgrade capability can be enabled through the application firmware. The module can be controlled from an external host device via the I2C Slave or the SPI Slave data interfaces. The I2C master port allows the module to control other system audio devices such as a sub-woofer amplifier system without having to add another MCU to the product design. Up to 9 additional GPIOs are available on the SWA54 module (not including I2C and I2S signals) for implementing different UI features on the target application. The resources mentioned above can be leveraged to implement low cost sub-woofer designs as outlined below. Typical Sub-Woofer Implementation A basic SKY76303-21 Wireless Subwoofer system block Diagram is shown in Fig. 2. Figure 1: SKY76303-21 Wireless Subwoofer Solution Block Diagram SWA54 Module Datasheet Rev 1.2 4 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 SWA54-RX module performs the control function using the I2C master communication port in conjunction with multiple GPIOs. The SWA54 module is configured to accept nominal 5V power from the main application board. An optional reset signal can be supplied to the SWA54-RX module and I2C or SPI slave communication can be used…
