TMUXHS4446: DP与USB Mux功能确认

Part Number: TMUXHS4446
Other Parts Discussed in Thread: TUSB1044

Tool/software:

您好：

如下图我我司TMUXHS4446设计方案：

从高通SOC输出4对USB-C高速信号至TMUXHS4446，通过CONF[2:0]做输出选择；如果CONF[2:0]=010，则设计为DP输出模式；如果CONF[2:0]=100，则设计为USB传输模式（通过Type-C接口）

请帮忙确认设计方案有无问题，能否支持上述功能

    Hi Young

      For TMUXHS4446, USB signal and DP should be separate from SOC source, USB signal goes to SSTX/SSRX, DP signal goes into DPINx.

       If USB and DP signal are from same channels from SOC, you need to use TUSB1044.

    Best
