[Fion]

Hi,

In PN5190B2 datasheet Figure 29. push-pull configuration,RXP connect to TX1 with C R and L,but in SPF-X-PNEV5190B_A1 (page7),RXP connect to TX2 with C and R, so which TX should RXP connect with?

Hello @Fion 

This is a symmetrical design, RXN can be connected to TX1 or TX2, and the same goes for RXP. You can refer to the Demo design.
