GENERAL DESCRIPTION

The ADV3000 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.

The ADV3000 is provided in an 80-lead LQFP, Pb-free, surface-

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

temperature range.

PRODUCT HIGHLIGHTS

1.

Supports data rates up to 2.25 Gbps, enabling 1080p deep

color (12-bit color) HDMI formats, and greater than

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 2.25 Gbps).

3.

Auxiliary switch routes a DDC bus and two additional signals

for a single-chip, HDMI 1.3 receive-compliant solution.
