GENERAL DESCRIPTION
The AD8197 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 to allow
the construction of larger arrays using the wire-OR technique.
Flexible channel bundling modes (for both the TMDS channels
and the auxiliary signals) allow the AD8197 to be configured as a

PRODUCT HIGHLIGHTS
1. Supports data rates up to 2.25 Gbps, enabling 1080p deep
color (12-bit color) HDMI formats, and greater than
UXGA (1600 × 1200) DVI resolutions.
2. Input cable equalizer enables use of long cables at the input
(more than 20 meters of 24 AWG cable at 2.25 Gbps).
3. Auxiliary switch routes a DDC bus and two additional signals
for a single-chip, HDMI 1.3 receive-compliant solution.
