GENERAL DESCRIPTION

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.

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.

PRODUCT HIGHLIGHTS

1.

Supports data rates up to 2.25 Gbps, enabling greater than

1080p HDMI formats with deep color, 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 2.25Gbps).

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.
