usb3.0/3.1轉typec接口接線圖

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、 本表假設所有SDP均使用屏蔽雙絞線，且有加蔽線。如果使用同軸線結構，則不存在加蔽線，并且同軸線的屏蔽層連接到接地引腳。

2、 USB Type-C插頭的引腳A5（CC）應通過電阻器Rp（56 k? ± 5%).Rp的功能描述和值見第4.5.3.2.2節和表4-24。

3、 USB Type-C插頭中不應存在觸點B6和B7。

4、 所有VBUS引腳應在USB Type-C插頭內連接在一起。旁路電容器為在電纜的USB Type-C插頭側的VBUS和接地引腳之間需要。旁路在包含USB標準a插頭的電纜中，電容器應為10nF±20%。旁路電容器應盡可能靠近電源焊盤。

5、 所有接地返回引腳應在USB C型插頭內連接在一起。

6、 屏蔽和GND接地應連接在USB類型-C和USB 3.1標準-A插頭內電纜組件的兩端。

7、 本表中未列出的所有USB Type-C插頭引腳均應打開（未連接）。
