HD3SS3220: Please check the schematic and answer the question.

1: it's better to have 0.33uf on RX incase high CM voltage from other sidw of type C connector, better move to connector side of mux.\

2: looks ok/

3: didn't see any other issue.

Regards

brian

◆ Question

(1)(Tomoyuki) Is it necessary to implement AC coupling in RX? It's not listed as a datasheet. Also, the USB3.x standard implements AC coupling only on the transmitter side.

　⇒ (brian) it's better to have 0.33uf on RX incase high CM voltage from other side of type C connector, better move to connector side of mux.\

　⇒ (Tomoyuki)

　　・Should C6 and C7 in the schematic be moved to the blue circles?

　　・Is it possible to change the value of RX's AC coupling capacitor from 0.33uF to 0.22uF?

　　   If it is 0.33uF, there is no 0402 (mm) size, so I would like to change it.

・Should C6 and C7 in the schematic be moved to the blue circles? yes

・Is it possible to change the value of RX's AC coupling capacitor from 0.33uF to 0.22uF? can not, should be 330nf or bigger value

.   If it is 0.33uF, there is no 0402 (mm) size, so I would like to change it. you can just remove AC cap on RX.
