PTN3222CUK-EVB demo board user manual
introducing signal integrity issues, one USB2 connector should be selected via the pair of
0 ohm resistors.
As factory default, USB2 signals are routed to the type C connector, but they can be
routed to standard A or uB connector as well by stuffing the proper 0 ohm resistor pair.
PTN3222 eUSB2 signals are routed to a pair of SMP connectors as shown in
Figure 3 as
eUSB2 interface to eUSB2 host or peripheral.

4.3 Board power
The PTN3222CUK-EVB can be configured to support eUSB2 host or eUSB2 device
mode via port configuration command or via I
2
C. The demo board can be configured via
jumpers to be powered from the DC barrel (5 V, 1 A or more), from a uB connector or
from the type C connector, the factory default.
In host mode, the board can be selected to provide 5 V to the USB connectors, the type
C connector. In device mode, the board can be selected to be powered from the uB
connector.
The board power configurations are shown in
Figure 4 .
