NOTE:
We didn't used the by-pass capacitor on the 3.3 V out, since the 3.3 V regulator and clamp
circuit will give a solution through the feedback.
USB block was designed to cover the line load, the typical value designed is 300 pF (max: 800 pF).
The calmp block operating after it detect the voltage variation
(actually the current fluctuation will be feedback into voltage variation, di/dt to dt/dt variation.
Bias control the slope.
Control signals means NRZI, EOP, XCON, IN/OUT.
Enable is for the Tx, Rx.
Internal pull-up resistor will be 1.5 k
