Other Parts Discussed in Thread: TIDA-00891,
In TIDA-00891, connection as below; USB_TXN connect with SSRXN
but in datasheet, the connection as below, TXN connect with SSTXN.
May I know which is right? Which should follow?
Thanks!

Both are correct. The HD3SS3220 is a passive switch, so it is possible to swap its TX & RX pins, you only have to care about the appropriate routing direction between the HOST and the connector.

Hi David,
Thanks for your reply~
I want to understand the internal connection of the MUX in HD3SS3220.
How TX and RX internally connect with TX1,RX1,TX2,RX2?
Does Tx connect with TX1 and TX2 and RX connect with RX1,RX2 or TX connect with RX1,RX2 and RX connect with TX1,TX2?
Besides, Could you pls help to review the schematics as attached? If any mistake in sch, pls figure them out. Thanks a lot!
Hi,
Is this a UFP or a DFP design?
USB org defines the TX1/TX2 to be transmitter and RX1/RX2 to be receiver, For the FPGA, is GT3_USB1_SSTX_P/N transmitter or receiver?
Thanks
David
Hi David,
It's a UFP design.
May I know the internal connection of TX and RX?
With this sch design, customer can't realize USB3.0 but only USB2.0. I was wondering if it's caused by the wrong connection of TX and RX.
Vbus_det should connect to VBus from connector, not supply voltage.
