9.1 Application Information

The TMUX646 is a 2:1, 10 channel MIPI switch designed to facilitate multiple MIPI compliant devices to connect

to a single CSI/DSI, C-PHY/D-PHY module.

9.2 Typical Application

Figure 9-1 represents a typical application of the TMUX646 MIPI switch. The TMUX646 is used to switch signals

between multiple MIPI modules and a single MIPI port on a processor. This expands the capabilities of a single

port to handle multiple MIPI modules.
