如上图所示,它是位于 Type-C Connector 中的两个pin(A5、B5),是 Host 和 Device 之间重要的配置通道。 Type-C 的 Receptacle 和 Plug 连接后,不仅仅有 cc 的电平识别,还有基于 cc 的 PD 协议通讯。因此 cc 的主要功能是,Detection Device,Check Positive and negative,
Type-C (二)，Configuration Channel (cc)什么是 Configuration Channel (cc) ？它是位于 Type-C connector 中的两个 pin，是 Host 和 Device 之间重要的配置通道。主要功能是，Detection Device Insert，Check Positive and negative，Control vconn，Configure Data Bus，Negotiate Power For Vbus，Discover and ...
USB Type-C Configuration Channel (CC) 功能分析 USB Type-C Configuration Channel (CC) 功能分析 架构总览 插入检测 识别电缆方向 在两个端口间协商建立DFP和UFP身份 发现和配置VBUS,电流模式或者PD模式 配置V…
CC(Configuration Channel):配置通道,这是USB Type-C里新增的关键通道,它的作用有检测USB连接,检测正反插,USB设备间数据与VBUS的连接建立与管理等. 在DFP的CC pin有上拉电阻Rp,在UFP有下拉电阻Rd。未连接时,DFP的VBUS是无输出的。连接后,CC pin相连,DFP的CC pin会检测到UFP的下拉电阻Rd,说明连接上了,DFP就打...
1对configuration pin(CC1,CC2) 一对Side Band Use pin(SBU1,SBU2) 从pin排布来看,上下12个pin是旋转对称的,因此USB-C 接口才能实现正反插。 CC pin 是USB-C用来识别线缆连接、插头方向、PD协议通信和Alt Mode 配置的重要pin,因为有了这个pin,USB-C接口才能自动识别正反插,自动配置充电电压电流,并且支持和配...
A note about CC1/CC2 pin voltage rating: In the USB Type-C connector, the CC1/CC2 pins are adjacent to the VBUS pins. Due to the small pin pitch of the connector, there is a risk that during cable connect or disconnect a short could occur between VBUS and CC1/CC2, resulting in ...
Connect the audio port of the shield to the audio port on the SUT by using a 4-pin male-to-male audio cable. Your setup should be similar to this image: Make sure USB Type-C ConnEx is recognized by Device Manager on the proxy controller. Right-click the Start button in the ta...
Type-C connector and it is not protected by power switch. For example, some of peripheral devices take only VBUS = 5V. The VBUS pin of TCPC in the peripheral device may be high as 20V due to out of control of power source. The VBUS pin AMR of theRT1715andRT1711Pare up to 24V,...
