Description
AI
The AD8190 is an 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.The AD8190 is provided in a space saving, 56-lead, LFCSP, surface-mount, Pb-free, plastic package and is specified to operate over the -40°C to +85°C temperature range.
