拿个I公司的TBT3来当例子好了,一个小小C口,需要与以下所有芯片交互(并且不限于这些) 1. PD controller - 负责电源管理2. Retimer - 负责信号增强3. EC - 需要拿到并且发出去正确的信号,某些协议里非必须 4. CPU - 需要负责最终各种功能的实现,USB4,USB3.2,DP-ALT MODE等 ...
I am designing a HDMI sink device (UFP) over USB type C alt mode. I was reading through CCG3 tech notes and datasheets and I am still confused how I can design the HDMI sink for usb type C using CCG3 type C port controller (if at all we can do that) I have a...
