7.2 Typical Application

Figure 7-1 represents a typical application of the TS3USB3031 MHL switch. The TS3USB3031 is used to switch signals between the two sets of USB paths, which go to either the baseband or application processor, and the MHL path, which goes to the HDMI to MHL bridge. The TS3USB3031 has internal 6-MΩ pulldown resistors on SEL0 and SEL1. The pulldown on SEL0 and SEL1 ensure the USB1 channel is selected by default. The TS5A3157 is a separate SPDT switch that is used to switch between the MHL CBUS and the USB ID line that is required for USB OTG (USB On-The-Go) application.
