4 SWA51 Functional Block Diagram and Functional Description Figure 1: SWA51 Module Block Diagram The SWA51 module is available in 2 variations; digital input transmitter module or digital output receiver module. 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.
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.

Figure 4: AV5100 Wireless Rear 2.
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.

6 Electrical, Audio and Timing Specifications 6.1 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.
