TUSB542: No connection

Part Number: TUSB542
Other Parts Discussed in Thread: TUSB8042A, TUSB321, , TUSB1002A, ISOUSB211

Hi Experts,

PCB0042.2_VPB_ISO_4k_SCH.pdf

 Unfortunately, I cannot establish a connection with USB 3.0 and therefore cannot communicate with the TUSB8042A. What could be the reason for this?

My information regarding the malfunction was a bit sparse.

Here is a brief update:

 

Tusb321 is configured as UFP.

I have CC2 = 0.9V / CC1 = 0V / SEL = 0V.

When I plug in USB at 180Crad, I have CC1 = 0.9V / CC2 = 0V / SEL = 1.8V

 

With Tusb542, I see an LFPS burst on the SSRX AP side.

Here are my settings:

 

I use the APISLCU31 with the following specifications to separate the USB 3.0 signals:

 

The TUSB1002A is set as follows:

 

EN = High

 

The ISOUSB211 is set as follows:

  • I have 3.3V for both V2OK and V1OK.

 

 

I get the following message via USB 2.0:

 

 

Unfortunately, I am unable to receive a signal via the TX with the Tusb8042A.

I hope you can help me here!
