8.2 Typical Application - HDMI

The TMUXHS4612 can be used to switch HDMI signals in both source and sink applications. In source applications HDMI port from a graphics processor can be demultiplexed into one of the two HDMI connectors. In a PC the TMUXHS4612 can be used to switch integrated graphics versus discrete graphics to a connector. In a sink application the device also can be used to select between two HDMI connectors to provide HDMI signals into a scaler (SOC) in HDMI sink application. This section provides detailed design implementation for a sink application where TMUXHS4612 provides 2:1 demultiplexing function.
