The Figure 10 describes in a simplified way what the USB
port components are. As shown in this diagram, there are
signals for upstream and downstream ports which must be
provided with Line Termination and EMI Filtering to meet
the requirements of the USB specification revision 1.1. In

As mentioned before, the ON Semiconductor STF202
device provides “upstream termination”, EMI Filtering and
ESD Protection to IEC6100−4−2 in an integrated solution

addition to the Line termination and EMI Filtering, it is also
needed to protect the USB I/O Lines against ESD
conditions, so TVS devices must be added for these
purposes.
