GENERAL DESCRIPTION
The AD8192 is a complete HDMI™/DVI link switch featuring equalized TMDS inputs and pre-emphasized TMDS outputs ideal for systems with long cable runs. The TMDS outputs can be set to a high impedance state to reduce the power dissipation and/or allow the construction of larger arrays using the wireOR technique. The AD8192 includes bidirectional buffering for the DDC bus and CEC line, with integrated pull-up resistors for the CEC line. The AD8192 is available in a space-saving, 56-lead LFCSP surface-mount, lead-free plastic package specified to operate over the −40°C to +85°C temperature range.
