Typical AD8193 Application for HDTV Sets GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The AD8193 is a low cost quad 2:1 TMDS switch for high 1. Data supports rates up to 2.25 Gbps, enabling greater than speed HDMI/DVI video applications. Its primary function is 1080p deep color (12-bit color) HDMI formats and greater to switch the high speed signals from one of two single-link than UXGA (1600 2300) DVI resolutions. (HDMI or DVI) sources to the single-link output. The AD8193 2. Fully buffered unidirectional inputs and outputs. is a fully buffered switch solution with 50 input and output 3. Supports more than 20 meters of a typical 24 AWG input terminations, providing full-swing output signal recovery and cable at 1080i, more than 10 meters at 1080p, and more minimizing reflections for improved system signal integrity. than 6 meters at 1080p, 12-bit color. 4. Matched 50 on-chip input and output terminations The AD8193 is provided in a space-saving, 32-lead, LFCSP, improve system signal integrity. surface-mount, RoHS-compliant, plastic package and is specified 5. Single-pin source select bit. to operate over the 40C to +85C temperature range. 6. Input terminations are automatically switched out for the unselected input. 7. Low added jitter. Rev.
