GENERAL DESCRIPTION
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.

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.
