Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.






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 construc-tion 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.

The AD8191 is provided in a 100-lead LQFP, Pb-free, surface mount package specified to operate over the −40 to +85 temperature range.
