GENERAL DESCRIPTION
The AD8190 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 AD8190 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
1.
Supports data rates up to 1.65 Gbps, enabling UXGA
(1600 × 1200) DVI resolutions and 1080p HDMI formats.
2.
Input cable equalizer enables use of long cables at the
input (more than 20 meters of 24 AWG cable at 1080p).
3.
Auxiliary switch allows routing of the DDC bus and two
additional single-ended signals for a single chip, fully
HDMI 1.2a receive-compliant solution.
