GENERAL DESCRIPTION
The AD8191 is a HDMI/DVI switch featuring equalized TMDS inputs and pre-emphasized TMDS outputs, ideal for systems with long cable runs. Outputs can be set to a high impedance state to reduce the power dissipation and/or allow the construction of larger arrays using the wire-OR technique. Flexible channel bundling modes (for both the TMDS channels and the auxiliary signals) allow the AD8191 to be configured as a 4:1 single HDMI/DVI link switch, a dual 8:1 switch, or a single 16:1 switch.

FEATURES
