Hello -
I'm working on a design that utilizes the THS7374 with ac-coupled inputs and outputs to both CVBS and S-Video signals. The outputs will drive two separate sink devices, so I've utilized a connection on the outputs similar to what is shown in Figure 62.
I'm confused, however, because the electrolytic capacitors in the AC-coupled outputs are different in the reference designs in the datasheet:
Which of these orientations is correct? Should the positive end of the capacitor be connected to the output of the THS7374 or should it be connected to the output connector?
I put together a design with the positive end connected to the output connector and thus far it is working, but I don't want to do this if it is incorrect/dangerous.
