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.
APPLICATIONS
Multiple input displays
Projectors
A/V receivers
Set-top boxes
Advanced television (HDTV) sets
