秘诀在于CC公头上。让我们来看CC公头的结构。 对比母座接线图,我们可以看出,公头只有一个CC,另外一个CC变成了VCONN,于是,当公头插入母座的时候,公头上的CC可能跟母座上的CC1连在一起,也可能跟母座的CC2连接在一起,分别对应着正插和反插两种情况。母座上需要用一颗芯片来检测是CC1建立了连接,还是CC2建立了连...

Devices utilizing USB C must include a 5.1K pull-down resistor Rd on the CC line for devices with only a USB Type-C connection. For devices with a Type-C receptacle, Rd should be advertised on both CC1 and CC2 lines. What is the process for USB-C devices to manage VBUS...
Cables with an eMark IC will have an internal 1k pull-down resistor Ra on the VCONN pin, so Ra has a lower value than Rd which is typically 5.1k. After inserting this type of cable, the Source will see both CC1 and CC2 pin voltages dropping. The voltage levels will tell the host ...
On both CC1 and CC2, a source must expose Rp pull up resistors, whereas a sink must expose Rd pull down resistors. Electronic cables need to provide a resistor, Ra, to ground on VCONN. From a source point of view, the state of attached devices can be ...
– 双角色端口– DRP 根据Type-C 规范,TUSB320 器件会交替配置为DFP • 通道配置(CC) 或UFP。CC 逻辑块通过监视CC1 和CC2 引脚上的 – USB 端口连接检测 上拉或下拉电阻,以确定何时连接了USB 端口、电缆 – 电缆方向检测 的方向以及检测到的角色。CC 逻辑根据检测到的角色 – 角色检测 来确定Type-C ...
There are two CC pins in each receptacle, but only one is connected through the cable to establish communication. The other pin can be re-assigned as the VCONN pin for powering electronics in the USB Type-C™ plug of electronically-marked cables. Specific Rd and Rp res...
