GENERAL DESCRIPTION

The AD8193 is a low cost quad 2:1 TMDS? switch for high speed HDMI?/DVI video applications. Its primary function is to switch the high speed signals from one of two single-link (HDMI or DVI) sources to the single-link output. The AD8193 is a fully buffered switch solution with 50 Ω input and output terminations, providing full-swing output signal recovery and minimizing reflections for improved system signal integrity.
