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.
