GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

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.

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.

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.
