AD8197B datasheet

Description :

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°Ctemperature range.
