usb3.0/3.1转typec接口接线图

1、This table assumes 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.

2、Pin A5 (CC) of the USB Type-C plug shall be connected to VBUS through a resistor Rp (56 k? ± 5%).
See Section 4.5.3.2.2 and Table 4-24 for the functional description and value of Rp.

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 Standard-A plug. The bypass
capacitor shall 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、Shield and GND grounds shall be connected within the USB Type -C and USB 3.1 Standard-A plugs on
both ends of the cable assembly.

7、All USB Type-C plug pins that are not listed in this table shall be open (not connected).

1、 本表假设所有SDP均使用屏蔽双绞线，且有加蔽线。如果使用同轴线结构，则不存在加蔽线，并且同轴线的屏蔽层连接到接地引脚。

2、 USB Type-C插头的引脚A5（CC）应通过电阻器Rp（56 k? ± 5%).Rp的功能描述和值见第4.5.3.2.2节和表4-24。

3、 USB Type-C插头中不应存在触点B6和B7。

4、 所有VBUS引脚应在USB Type-C插头内连接在一起。旁路电容器为在电缆的USB Type-C插头侧的VBUS和接地引脚之间需要。旁路在包含USB标准a插头的电缆中，电容器应为10nF±20%。旁路电容器应尽可能靠近电源焊盘。

5、 所有接地返回引脚应在USB C型插头内连接在一起。

6、 屏蔽和GND接地应连接在USB类型-C和USB 3.1标准-A插头内电缆组件的两端。

7、 本表中未列出的所有USB Type-C插头引脚均应打开（未连接）。
