The MicroUSB connector supports audio accessories in addition to USB data. In order to support audio accessories via the µUSB port, the USB switch is required to route audio and USB data, for which the TS5USBA224 and TS3USBA225 make an excellent choice. These USB switches have low RON and can be used to pass audio signals as well. As shown in the diagram on this slide, these USB switches connect the D+ and D- pins to the left and right channels of the audio codec when audio signal is connected. The same switch connects these pins to the differential data lines of the USB transceiver when a USB data cable is connected. This is controlled via the control logic.
