1. 供電端(Source or Provider)和受電端(Sink or Consumer)藉由CC腳位溝通,調配USB type-C埠的輸出電壓,因此在測試USB Power Delivery的Protocol Safeguard時,許多測試項目會藉由量測CC和VBUS腳位,檢測USB type-C埠與埠之間的問答 (query and ack)程序符合標準動作流程。 CC 腳位的訊號會經由BMC 編碼和解碼,...

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 ...
USB3.0相较于USB2.0多了几个针脚,在Type-A接口上,接口的里面多了5个针脚,Type-B接口则在接口上方多了一块。 USB3.0采用的是两排共9个针脚的设计。 3、标识区分法,根据在插口旁边的符号来区分,如下图。USB3.0的“SS”代表着“SuperSpeed”。 3. USB2.0通信协议简介(包-事务-传输) 3.1 包(Package) 包是...
