Description

The AD8197B is an HDMI™/DVI switch featuring equalized TMDS® inputs and pre-emphasized TMDS outputs, ideal for systems with long cable runs. The AD8197B offers individual control of the on/off state of the TMDS input termination resistors via I2C® control. 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. 

Features
1. 4 inputs, 1 output HDMI/DVI links
2. Enables HDMI 1.3-compliant receiver
3. Equalized inputs allow use of long HDMI cables (20 meters at 2.25 Gbps)
4. Fully buffered unidirectional inputs/outputs
5. 4 auxiliary channels per link
6. Bidirectional unbuffered inputs/outputs
7. Reduced power dissipation
8. Removable output termination
9. 100-lead, 14 mm × 14 mm LQFP, Pb-free package

Applications 

1. Multiple input displays
2. Projectors
3. A/V receivers
4. Set-top boxes
5. Advanced television (HDTV) sets
