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

temperature range.

GENERAL DESCRIPTION

The AD8191 is a 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 construc-

tion of larger arrays using the wire-OR technique. Flexible

channel bundling modes (for both the TMDS channels and the

auxiliary signals) allow the AD8191 to be configured as a 4:1 single

HDMI/DVI link switch, a dual 8:1 switch, or a single 16:1 switch.

PRODUCT HIGHLIGHTS

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.
