TYPICAL APPLICATION
Figure 1 represents a typical application of the TS3USB3000 MHL switch. The TS3USB3000 is used to switch
signals between the USB path, which goes to the baseband or application processor, or the MHL path, which
goes to the HDMI to MHL bridge. The TS3USB3000 has internal 6MΩ pull-down resistors on SEL and OE. The
pull-down on SEL ensure the USB channel is selected by default. The pull-down on OE enables the switch when
power is applied. 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.
