MAX4886

Additional Applications

Information

In a typical application (see Figure 5), the MAX4886

and MAX4929 are used to route the TMDS signals and

low-frequency signals between two HDMI inputs.

In another application (see Figure 6), the MAX4886 is

used in a notebook to route high-frequency DVI port on

the computer or to the connector on the docking sta-

tion. The MAX4886 routes four differential signals (RGB

and CLK) either to the DVI connector or to the docking

station port. The switch is inherently bilateral and may

be used as a 2:1 or 1:2 mux without penalties.
