[Ronja] Twister2 U63-U65

[Sordrag at gmx.de]

Hi all!

I'm trying to understand how the Twister works. My problem is the cascade of U63 to U65 (and also the one of U51 and U53). I don't get the idea behind this. I already read the FAQs but they were not enough.

Can anyone explaine me in detail how the identification of data in the signal by the use of the cascades works?
And why is there the OR (U54) before this cascade? It just works as an inverter and the signal gets inverted back thru U52. Is this necessary?

And why are there after the RX discriminator (U51, U53) those two Schmitt Triggers of U52. I think if I do the hole cicuit on a PCB I have short wires so those Triggers aren't necessary!?

Thx for your help.
