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 external masters. In addition, MCLK can be output from the module to provide a reference clock source to an external ADC or DAC. Figure 1 shows the block diagram of the SWA51 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 AV5100 transceiver IC results in few external components being required for the SWA51 module design. 2 printed PCB antennas are used to achieve increased range, and to achieve antenna spatial diversity. The simple RF path consists only of the antennas, associated tuning components, shield can, the RF switch and two baluns, one connected to each of the RF input and RF 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 r 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 119 additional GPIOs are available on the SWA51 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. 4.1 Typical Sub-Woofer Implementation A basic AV5100 Wireless Subwoofer system block Diagram is shown in Fig. 2. Figure 2: 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 SWA51-RX module performs the control function using the I2C master communication port in conjunction with multiple GPIOs. The SWA51 module is configured to accept nominal +3.3V or +5V power from the main application board. An optional reset signal can be supplied to the SWA51-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 the power supply to external system blocks such as the PWM IC and the output stage. The SWA51-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 SWA51 can also be completely powered down by turning off the main 3.3V supply. If the wireless link is lost (ex. when the sound bar is powered down), the SWA51_RX module can, after a timeout period, power down the amplifier and output stage sections to conserve power and to help meet Energy Start requirements. The I2C master port from the SWA51_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 SWA51-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 SWA51-RX module as a -12.28800MHz clock if required.

Figure 4: AV5100 Wireless Rear 2.1 Solution Block Diagram This implementation involves transmitting three channels over the air, one full-band stereo channel (2 x 96dB, 20KHz) used for the rear surround audio, and one mono 96dB, 5KHz channel for subwoofer audio1. The hardware implementation on the client side is very similar to the subwoofer implementation, only two PWM ICs and two audio amplifiers are used; one to drive the mono subwoofer and one to drive to stereo left and right surround speakers. Still, no micro-controller is required; the Av5100 can act as a master controller for the PWM and amplifier ICs via I2C, and as an I2S master with MCLK sourced either internally by the AV5100 or externally from an external clock source. The actual subwoofer and surround speaker drivers can be housed inside the same physical unit, or be housed in separate enclosures with wired connections to the client unit. Fig. 3 still applies to the surround rear 2.1 application, only 2 PWM and output stages are used. 4.3 SWA51 Module Connections and Interfaces Signal Type Description +3.3V Supply The SWA51 hardware is configured to accept a +3.3V 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. 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 SSC (Single Side Carrier) modulation scheme used in the SWA51 supports three one-directional full-band channels (96dB, 20 KHz). 5 SWA51 Connector Information Table 1: SWA51 Connector Information No Pin Name Pin Type AV65100 Pin SWA51-TX Pin Description SWA51-RX Pin Description GPIO2/S_SSB Digital I/O 12 GPIO or SPI Slave Chip Select GPIO or SPI Slave Chip Select GPIO3/S_SCLK Digital I/O 11 GPIO or SPI Slave Serial Clock GPIO or SPI Slave Serial Clock GPIO4/S_SDA/S_MOSI Digital I/O 10 GPIO, I2C Slave Serial Data or SPI Slave Data In GPIO, I2C Slave Serial Data or SPI Slave Data In GPIO5/S_SCL/S_MISO Digital I/O GPIO, I2C Slave Serial Clock or SPI Slave Data Out GPIO, I2C Slave Serial Clock or SPI Slave Data Out GPIO16/M_SDA Digital I/O GPIO, I2C Master Serial Data GPIO, I2C Master Serial Data GPIO17/M_SCL Digital I/O GPIO, I2C Master Serial Clock GPIO, I2C Master Serial Clock GPIO20/LINK_LED Digital I/O 56 GPIO, or LINK_LED Output GPIO, or LINK_LED Output GPIO21/PAIR Digital I/O 55 GPIO, or input from PAIR Button GPIO, or input from PAIR Button GPIO18/BCLK1 Digital I/O GPIO or I2S Port 1 Bit Clock GPIO or I2S Port 1 Bit Clock 10 GPIO19/WCLK1 Digital I/O GPIO or I2S Port 1 Word Clock GPIO or I2S Port 1 Word Clock 11 GPIO10/MCLK Digital I/O 53 GPIO or Master Clock Out GPIO or Master Clock Out 12 GND GND Paddle (57) GND GND 13 GPIO11/BCLK0 Digital I/O 52 GPIO or I2S Port 0 Bit Clock GPIO or I2S Port 0 Bit Clock 14 GPIO12/WCLK0 Digital I/O 51 GPIO or I2S Port 0 Word Clock GPIO or I2S Port 0 Word Clock 15 GPIO13/ADAT0 Digital I/O 50 GPIO or I2S Port 0 Audio Data GPIO or I2S Port 0 Audio Data 16 GPIO14/ADAT1 Digital I/O 49 GPIO or I2S Port 1 Audio Data GPIO or I2S Port 1 Audio Data 17 GPIO15/ADAT2/CEN Digital I/O or Digital Input 48 or 38 GPIO, I2S Port 2 Audio Data or chip enable (1) GPIO, I2S Port 2 Audio Data or chip enable (1) 18 GPIO22/D+ Digital I/O 47 or 43 GPIO or USB Data Plus (2) GPIO or USB Data Plus (2) 19 GPIO23/D- Digital I/O 46 or 42 GPIO or USB Data Minus (2) GPIO or USB Data Minus (2) 20 GPIO24 Digital I/O 41 GPIO (3) GPIO (3) 21 RESETN_EXT Digital Input 37 RESET signal active low (4) RESET signal active low (4) 22 GND GND Paddle (57) GND GND 23 VDD Supply Input 31, 45, 54 +3.3V input supply voltage +3.3V input supply voltage 24 VDD Supply Input 31, 45, 54 +3.3V input supply voltage +3.3V input supply voltage Notes: (1) Pin 17 is hardware configured as GPIO15/ADAT2 by default; utilizing this pin as a CEN requires a different stuffing option.

(3) Pin 20 (GPIO24) can be utilized to implement a “Data Waiting” interrupt signal for I2C and SPI Slave data communication. (4) Pin 21 (RESET_EXT) can be pulled to GND with a switch or an open drain/collector type device to provide a hard reset signal to the AV5100. This pin is pulled up to VDDIO (3.3V) internally in the AV5100 and should not be actively driven high. 20.0mm Figure 4 – SWA51 Module Outline and Mechanical Dimensions - PCB thickness is 1.0mm - The top of shield is 2.4mm above PCB - The maximum height from the bottom of the PCB to the top of the shield can is 3.4mm. 6 Electrical, Audio and Timing Specifications 6.1 Absolute Maximum Ratings Absolute Maximum Ratings (AMR) are stress ratings only.

The rise and fall times of the I2S signals are determined by ESD/EMI mitigation components on the modules, as well as external loading, and will be higher than the specified numbers 6.10 I2C Master/Slave Communication Interface Timing (S_SCL, S_SDA) The SWA51 has both I2C slave and master interfaces available with their respective pins S_SCL, S_SDA and M_SCL, M_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. The SWA51 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 SWA51 (Ex. GPIO24), can be used to notify the I2C master when a pending message is ready to be sent. The SWA51 slave interface responds to the 7-bit slave address 1000000 (0x40) as shown in Figure 1 below.
