Figure 1. Typical TS3USB3031 Application
HDMI
The diagram above represents a typical application of the TS3USB3031 MHL switch. The TS3USB3031 is used
to switch signals between the 2 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 6MΩ pull-down resistors
on SEL0 and SEL1. The pull-down 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 MHL’s CBUS and the USB ID line that is
needed for USB OTG (USB On-The-Go) application.
