For a new design I’m using the ADV7393 with the ADA4412-3 for SD & HD video outputs.
one of the outputs needs to be duplicated to two separate monitors. For that I want to use the 2 loads application (figure 18 of the ADA4412-3 datasheet).
I have some questions regarding this application:
How does this support the same output amplitude for one load and two loads?
Are there any issues if I use this application but only one monitor is plugged in and the other one is left not connected. Doesn’t this create a long stub?
Where is it better to place the ADA4412-3- close to the encoder or closer to the connector. There is ~15cm and 2 connectors from encoder to external connector panel. The design is with 75ohm controlled impedance.
