2:1 HDMI/DVI Switch with Equalization

The AD8196 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 AD8196 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.

Product Highlights

* Supports data rates up to 2.25 Gbps, enabling greater than 1080p deep color (12-bit color) HDMI formats, and greater than UXGA (1600 × 1200) DVI resolutions.

* Input cable equalizer enables use of long cables at the input (more than 20 meters of 24 AWG cable at 2.25 Gbps).

* Auxiliary switch allows routing of the DDC bus and two additional single-ended signals for a single chip, HDMI 1.3 receive-compliant solution.
