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.The AD8193 is provided in a space-saving, 32-lead, LFCSP, surface-mount, RoHS-compliant, plastic package and is specified to operate over the −40°C to +85°C temperature range.Product HighlightsData supports rates up to 2.25 Gbps, enabling greater than 1080p deep color (12-bit color) HDMI formats and greater than UXGA (1600 × 2300) DVI resolutions.Fully buffered unidirectional inputs and outputs.Supports more than 20 meters of a typical 24 AWG input cable at 1080i, more than 10 meters at 1080p, and more than 6 meters at 1080p, 12-bit color.Matched 50 Ω on-chip input and output terminations improve system signal integrity.Single-pin source select bit.Input terminations are automatically switched out for the unselected input.Low added jitter.ApplicationsAdvanced television (HDTV) setsMultiple input displaysProjectorsA/V receiversSet-top boxes
