Hardware design
When connecting the UG-IC and the RJ45-connector it is important to
make sure the signal lines RD1-/RD1+ resp. TD1-/TD1+ also RD2-/RD2+
resp. TD2-/TD2+ run as short a possible, parallel and equal in length.
Because this is for analog signals, it is also advisable not to place digital
lines in close proximity.
The 74HCT595 used in this example has an undefined on-position, but
therefor can set the outputs to the tri-state condition via the OutEnable-
Pin 13. If it is more important to have a defined on-position in an applica-
tion, and the OutEnable-pin is not necessary, the 74HCT594 can be used
here.
