Original question:
TUSB321AI: Need schematic verification for USB 3.1 Type-C circuit.
We have the circuit fabricated, but we aren't able to get it working. We are able to observe changes on the DIR pin on TUSB321AI as well as SEL pin on TUSB542 based on the type-C connector's orientation, which implies orientation detection is working.
But when we connect the USB 3.1 camera to the PCB, the device does not get recognized on the PC.
Please let us know how we can proceed debugging the TUSB542 or if there are any other design errors.
from old block diagram, you changed FPC connector to typ-C connector ? Also need to change PORT pin to Gnd for UFP.
Hi Brian,
There are no changes done with respect to the block diagram attached in previous thread.
Also, PORT pin is already tied to GND for UFP configuration using jumpers provided on the PCB.
To mention, we use a USB-A to Type-C cable, and we are getting output from TUSB321AI for the Type-C orientation on the DIR pin/SEL pin of TUSB542.
For Flex connector, did cable connect SSRX to SSTX of camera or SSRX of camera?
SSRx of TUSB542 connects to SSRx of Camera, I assume the Tx-Rx crossing takes place in the USB-A to Type C cable.
