The noise is invisible! Remember: we’re assuming both signals are being affected by the noise equally. To make that assumption, we need to space our differential pair wires as closely as ...

Enter Differential Signaling where we use two conductor instead ... By selecting one pin it automatically assigns the pair to complete the Differential path. In this CPLD there is really just ...

The pin name of every pin indicates the signal category, i.e. single-ended reset, logical differential or logical single-ended. In a second step, a complementary pin is added to the cell for every pin ...
