4:1 DVI/HDMI Switch with Equalization

The AD8191 is a DVI/HDMI 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 allow the AD8191 to be configured as a 4:1 single DVI/HDMI link switch, a dual 8:1 TMDS channel switch, or a single 16:1 TMDS channel switch.

The AD8191 is provided in a 100-lead LQFP lead-free package specified to operate over the 0°C to 70°C temperature range.
