Other Parts Discussed in Thread: TUSB322I
dear
Pin define in TUSB542RWQ datasheet show as below
However , Pin define is different in TUSB542RWQ product information which find on the official website show as below,which is correct?
The circuit diagram of TUSB322IRWBR is as follows. After connecting the USB with forward (reverse) insertion, CC1=0, CC2=0.4V, and TYPEC_SEL=0.Backplug (positive plug) connection USB,CC1=0.4V, CC2=0, TYPEC_SEL=1.8V;
The chip can realize DIR pin high and low level selection;But USB 3.0 has not been conduction, plug USB in any case can only identify to USB 2.0, other circuits are normal, can be sure, the problem is in the two chips;
any advise ? thanks in advance
