Introduction

The AD8197B is an HDMI/DVI switch featuring equalized TMDS inputs and pre - emphasized TMDS outputs, ideal for systems with long cable runs. The AD8197B offers individual control of the on/off state of the TMDS input termination resistors via I²C control. Outputs can be set to a high impedance state to reduce the power dissipation and/or to allow the construction of larger arrays using the wire - OR technique. The AD8197B is provided in a 100 - lead LQFP, Pb - free, surface - mount package, specified to operate over the - 40°C to + 85°C temperature range.
