I'm not actively making videos now. I haven't studied Ethernet, but in principle there's no reason why the center tap has to be ground. As long as it's relatively stable on the end of the line, it really doesn't matter what its potential is.
1. source output impedance as low as possible; 2. load input impedance as high as possible; 3. lines matched what do you mean by "lines matched"? do you mean the lines suffer from the common mode noise? thanks in advance.
Is there any chance of you posting a video explaining Ethernet links where at each end is a centre tapped transformer BUT the centre tap is tied to 3V3 . I can not visualise how the signals look on the line . I think the signaling sends a pulse on the TX+ and opposite on TX- but do not understand where the return path is .

CMRR definition incorrect
CMRR DEFINITION IS INCORRECT....
