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. 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 AV5100 transceiver IC results in few external components being required for the SWA52 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 AV5100 IC. A 16MHz crystal oscillator generates the AV5100 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 AV5100 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 subwoofer amplifier system without having to add another MCU to the product design. Up to 9 additional GPIOs are available on the SWA52 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 subwoofer designs as outlined below. CONTENTS SUBJECT TO CHANGE WITHOUT NOTICE CONFIDENTIAL 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. The SWA52 module is configured to accept nominal 5V power from the main application board. An optional reset signal can be supplied to the SWA52-RX module and I2C or SPI slave communication can be used to control the module if required. Several GPIOs can be used to drive LEDs, or to connect to UI buttons. Typically 2 LEDs may be used and 1 button for pairing purposes. Another button could be used, for example, to implement a “bass enhance” feature. Another GPIO can be used to control he power supply to external system blocks such as the PWM IC and the output stage. The SWA52-RX module can remain powered up during a standby or low power operating mode; however, a true power-down mode can be implemented by configuring pin 17 (GPIO15/ADAT2/CEN) to be used as a chip-enable pin that can be used to power down the AV5100. The SWA52 can also be completely powered down by turning off the main 5V supply. If the wireless link is lost (ex. when the sound bar is powered down), the SWA52_RX module can, after a timeout period, power down the amplifier and output stage sections to conserve power and to help meet Energy Star requirements. The I2C master port from the SWA52-RX module (pins 5 and 6 on the connector) can communicate, control, and initialize external audio ICs such as the PWM chip in this example. Other GPIOs can be used to detect fault conditions (over temperature etc) and notify the module. The audio is routed from the SWA52-RX module to the amplifier circuit with the I2S output port which can be configured as either a master or a slave as required. MCLK can also be generated from the SWA52-RX module as a 12.00 MHz clock if required.

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. I2S In Port The I2S input port can be configured as a master or slave. Consequently BCLK and LRCK can be either inputs or outputs. In addition, MCLK can be sourced by the module on pin 16. Since the AV5100 IC contains a sample rate converter, MCLK is not required to be supplied to the module when it is an I2S slave. CMOS 3.3V logic levels are used for all I2S signals. I2S Out Port The I2S output port can be configured as a master or slave. Consequently BCLK and LRCK can be either inputs or outputs. In addition, MCLK can be sourced by the module on pin 16. Since the AV5100 IC contains a sample rate converter, MCLK is not required to be supplied to the module when it is an I2S slave. CMOS 3.3V logic levels are used for all I2S signals. I2C Slave Port The I2C slave port can be used for external host communication and for module testing. 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. It is assumed that external pull up resistors are included on the application board. 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 outputs or inputs with configurable pull-ups/pull-downs.

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. The SWA52 will apply clock-stopping (by holding the clock line S_SCL LOW to force the master into a wait state) if necessary due to internal high-priority tasks. The slave/master interface can be used both for writing (e.g. sending commands) or reading (e.g. requesting status). An additional GPIO pin on the SWA52 (Ex. GPIO24), can be used to notify the I2C master when a pending message is ready to be sent. The SWA52 slave interface responds to the 7-bit slave address 1000000 (0x40) as shown in Figure 1 below.
