After a USB PD Cable Reset, the plug being supplied V CONN responds to SOP’ independent of whether it is the plug atta ched to the Source or Sink.The controllers can sense whether they are SOP’ or SOP” based on the presence of V CONN at the plug’s V CONNpin as only one port supplies V CONN.Figure 5-6 illustrates the process that shall be followed to assign SOP’ and SOP” to the ends attached to theSource and Sink, respectively, at power on. In the Unassigned state, the active cable will not respond to any USB PD communication sent to SOP’ or SOP”.

Multi-modal cables (e.g., an active cable that supports an Alternate Mode in addition to USB SuperSpeed) that use the TX/RX signal pairs shall minimally support USB 3.1Gen 1 operation. They are encouraged to support both Gen 1 and Gen 2 operation.Figure 5-7 illustrates a typical managed active cable. The isolation elements (Iso) shall prevent V CONN from traversing end-to-end through the cable.

In all cases, these messages shall only use SOP’ and SOP”. Theyshall not use SOP.SOP’ and SOP” are defined to allow a vendor to communicate individually with each end the cable.For active cables that support both SOP’ and SOP”, after attach or a USB PD Cable Reset, the plug directlyconnected to the Source shall only respond to SOP’ and the plug directly connected to the Sink shall only respond to SOP”.The assignment of SOP’ and SOP” to each plug remains persistent until V CONN is removed or a subsequent USB PD Cable Reset.The Discover Identity message shall start with SOP’.To Text:5.2 Managed Active CablesManaged active cables may have a single USB PD controller in the cable that responds to USB PD Structured VDMs sent to SOP’ if independent management of each end is not required.All managed active cables shall identify if they respond to SOP’ only or to both SOP’ and SOP” using the Discover Identity command defined in USB Power Delivery.5.2.1 Requirements for Managed Active Cables that respond to SOP’ and SOP”Managed active cables shall implement the Cable State Machine defined in 4.5.2.4 and Figure 4-19.A managed active cable which supports two USB PD controllers shall ensure the cable plugs are uniquely assigned via the mechanism described here, one as SOP’ and the other as SOP”.USB PD supports three types of USB Type-C-related swaps that may or may not impact V CONN:• USB PD V CONN_Swap – The port previously not supplying V CONN sources V CONN and the assignment of SOP’ and SOP” remain unchanged.• USB PD DR_Swap –The assignment of SOP’ and SOP” remain unchanged.• USB PD PR_Swap –The assignment of SOP’ and SOP” remain unchanged.Managed active USB Type-C to USB Type-C cables shall by default support USB operation.

聊聊TYPEC数据线的铜丝规格怎么选择⾃从TYPE C数据线开始跑3A，5A电流以后，铜丝规格如何选择来满⾜电流和功率的问题就开始经常有⼈问到，今天我们就⼀起聊聊TYPE C数据线的铜丝规格怎么选择，USB数据线，最基本的电器参数就是电阻，压降，电压等，其实被客⼈问最多的当然就是对应数据线可以承受多少的电流，⽤多⼤的导体⽐较划算，今天我们就⼀起聊聊。

在TYPE C数据线的数据线⾥⾯，涉及到电流传输的PIN⾓定义为VBUS和GND，我们再⼀起回顾下USB Type-C脚位说明，然后再回到这个主题以上信号按照功能主要可以分为5类：第⼀类：Power有关的信号，包括a）VBUS，USB线缆的bus power（和我们通常意义上VBUS保持⼀致）。

b）VCONN（只有在插头上才会有该信号），⽤于向插头供电（由此可以推测出有些插头中可能会有电路）。

c）GND，接地第⼆类：USB 2.0数据线，D+/D-，它们在插头端只有⼀对，和旧的USB 2.0规范⼀致。

但为了⽀持正反随意插。

在插座端定义了两组，这样插座端可以根据实际情况进⾏合适的mapping。

第三类：USB3.1数据线，TX+/-和RX+/-，⽤于⾼速的数据传输。

插头和插座端都有两组，⽤于⽀持正反随意插。

第四类：⽤于Configuration的信号，对插头来说，只有⼀个CC，对插座来说，有两个CC1和CC2。

第五类：扩展功能所需的信号，具体使⽤场景由相应的扩展功能决定。

⼀个电源的电压经过⼀段线路或其他部件的传送电压有⼀部分就会被消耗从⽽降低，这降低的部分就是这段线路的电压降，测量电源起点处的电压与终点处的电压，两者之差就是电压降.举个简单的例⼦，例如变电站的输出电压是220V，⽽你家的电压是215V，那么从变电站到你家的这段电路的电压降就是220V-215V=5V.电压降应该这样解释：电线本⾝存在电阻，当电流沿导线流动时，必须施加⼀个电压来克服这个电阻，否则电流就不能通过；在同样⼀根电线上，通过的电流越⼤，需要来克服这个电阻的电压就越⾼（V=I*R），克服这个电阻的电压对于供电电源来说，就是造成了“电压降”（送过去的电压降低了），⽤电量越⼤（I 加⼤）电压降也就越⼤，导线电阻率越⼤、导线截⾯积越⼩、导线越长（R 加⼤）电压降也越⼤.从以上可以看出，衡量电压降⽐单纯的电流靠谱稳定和更加全⾯。

The USB 2.0 Type-C plug is shown in Figure 3-9. The following design simplifications may be made when only USB 2.0 is supported:∙Only the contacts necessary to support USB PD and USB 2.0 are required in the plug.All other pin locations may be unpopulated. See Table 3-5. All contacts are required to be present in the mating interface of the USB Type-C receptacle connector.∙Unlike the USB Full-Featured Type-C plug, the internal EMC springs may be formed from the same strip as the signal, power, and ground contacts. The internal EMC springs contact the inner surface of the plug shell and mate with the receptacle EMC pads when the plug is seated in the receptacle.∙ A paddle card inside the plug may not be necessary if wires are directly attac hed to the contact pins.Figure 3-9 USB 2.0 Type-C Plug Interface Dimensions3.2.2Reference DesignsThis section provides reference designs for a few key features of the USB Type-C connector. The reference designs are provided as acceptable design examples. They are not normative.3.2.2.1Receptacle Mid-Plate (Informative)The signals between the top and bottom of the receptacle tongue are isolated by a mid-plate inside the tongue. Figure 3-10 shows a reference design of the mid-plate. It is important to pay attention to the following features of the middle plate:∙The distance between the signal contacts and the mid-plate should be accurately controlled since the variation of this distance may significantly impact impedance of the connector.∙The mid-plate in this particular design protrudes slightly beyond the front surface of the tongue. This is to protect the tongue front surface from damage caused by miss-insertion of small objects into the receptacle.∙The mid-plate is required to be directly connected to the PCB ground with at least two grounding points.∙The sides of the mid-plate mate with the plug side latches, making ground connections to reduce EMC. Proper surface finishes are necessary in the areaswhere the side latches and mid-plate connections occur.Figure 3-10 Reference Design of Receptacle Mid-Plate3.2.2.2Side Latch (informative)The side latches (retention latches) are located in the plug. Figure 3-11 shows a reference design of a blanked side latch. The plug side latches should contact the receptacle mid-plate to provide an additional ground return path.Figure 3-11 Reference Design of the Retention LatchFigure 3-12 Illustration of the Latch Soldered to the Paddle Card Ground3.2.2.3Internal EMI Springs and Pads (Informative)Figure 3-13 is a reference design of the internal EMC spring located inside the USB Full-Featured Type-C plug. Figure 3-14 is a reference design of the internal EMC spring located inside the USB 2.0 Type-C plug.Figure 3-13 Reference Design of the USB Full-Featured Type-C Plug Internal EMCSpringFigure 3-14 Reference Design of the USB 2.0 Type-C Plug Internal EMC SpringIt is critical that the internal EMC spring contacts the plug shell as close to the EMC spring mating interface as possible to minimize the length of the return path.The internal EMC pad (i.e., ground plate) shown in Figure 3-15 is inside the receptacle. It mates with the EMC spring in the plug. To provide an effective ground return, the EMC pads should have multiple connections with the receptacle shell.Figure 3-15 Reference Design of Internal EMC Pad3.2.2.4Optional External Receptacle EMC Springs (Informative)Some applications may use receptacles with EMC springs that contact the outside of the plug shell. Figure 3-16 shows a reference receptacle design with external EMC springs. The EMC spring contact landing zones for the fully mated condition are normative and defined in Section 3.2.1.Figure 3-16 Reference Design of a USB Type-C Receptacle with External EMC Springs。
