USB TYPE-C和USB3.1 Micro-B插头线缆接线图

1. Pin A5 (CC) of the USB Type-C plug shall be connected to GND through a resistor Rd (5.1 kΩ ± 20%).
   See Section 4.5.3.2.1 and Table 4-25 for the functional description and value of Rd.
2. This table that shielded twisted pair is used for all SDP’s and
   there are drain wires. If coaxial wire construction is used, then no drain wires are present, and the
   shields of the coaxial wires are connected to the ground pins.
3. Contacts B6 and B7 should not be present in the USB Type-C plug.
4. All VBUS pins shall be connected together within the USB Type-C plug. A bypass capacitor is
   required between the VBUS and ground pins in the USB Type-C plug side of the cable. The bypass
   capacitor shall be 10nF ± 20% in cables which incorporate a USB Micro-B plug. The bypass
   capacitor should be placed as close as possible to the power supply pad .
5. All Ground return pins shall be connected together within the USB Type-C plug.
6. Pin 4 (ID) of the USB 3.1 Micro-B plug shall be terminated as defined in the applicable specification
   for the cable type.
7. Shield and GND grounds shall be connected within the USB Type-C and USB 3.1 Micro-B plugs on
   both ends of the cable assembly.
8. All USB Type-C plug pins that are not listed in this table shall be open (not connected).
