Guys,
I have a bit of a design challenge:
I have a USB 3.2 controller, on a custom PCB I am designing
for a customer.
The customer has requested that both a USB-A and a USB-C
connector be connected to that single controller, such
that the customer may choose which interface to use.
Now, this sounds simple enough, until you look at the signals.
The RX/TX lines for USB 3.2 are point to point, 90 ohm
terminated lanes.
I must admit, I am not a RF/high-speed PCB layout person.
Is there a way to make this work? Placing the connectors
and their pins close together (on opposite sides of the PCB),
and just do the best possible impedance matching?
I am at loss, any ideas/suggestions?
Cheers,
