TDA4VM: USB3.0

Part Number: TDA4VM

In REF CIRCUIT, 2 ports were used by applying USB C TYPE. However, we are going to use 1 port of USB3.0. Which port should I use between 0 and 1 ports of SERDES3?

ADD : Do I have to apply an external clk of 100Mhz?

If you don't need both serdes lanes, you can use either one. As for the reference clock, you don't need to use an external clock. The device can generate a reference clock internally.

Hello

We use USB lane 0 as USB 3.0 (not Type C).

Since it is not a Type C, should I change to lane 1?

Thanks for bringing this up. The note here isn't totally accurate. There is a way to swap the physical pins for lane 0 and 1. That said, lane 1 is the default, so if you can use 1 you should use it.
