GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD8191A 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.

1. Supports data rates up to 1.65 Gbps, enabling 1080p HDMI

formats and 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 1080p).

3. Auxiliary switch routes a DDC bus and two additional

signals for a single-chip, HDMI 1.2a receive-compliant

solution.

The AD8191A is provided in a 100-lead LQFP, Pb-free, surface-

mount package specified to operate over the −40°C to +85°C

temperature range.
