GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
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.
1. 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.
2. Input cable equalizer enables use of long cables at the
input (more than 20 meters of 24 AWG cable at 2.25 Gbps).
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.
3. Auxiliary switch allows routing of the DDC bus and two
additional single-ended signals for a single chip, HDMI 1.3
receive-compliant solution.
