Hi,
I am using USB 3.0 MUX, PI5USB30213AXEAEX with CX3. In the reference design of PI5USB30213AXEAEX, 0.22uF AC coupling capacitor is recommended for TX signals and 0.33uF AC coupling capacitor is recommended for RX signals from the connector and 0.22uF AC coupling capacitor is recommended for the TX signal near the CX3.
Can someone please confirm if this recommendation can be supported by CX3/FX3. Please refer below image for understanding the design
Thanks,
Menaka

Hello,
We recommend 0.1uF in our reference designs. But if the Mux that you prefer to use requires an AC coupling capacitor of 0.22uF in the SSTX lines, then it is okay to use it. This is supported by FX3/CX3.
