pn5180

[DatNguyen]

Hello everyone, I am currently designing an NFC card reader circuit using the PN5180. I am using a 1 nF capacitor for C88, but I am not using the 1 nF capacitor connected to pin 15 (RXN). Will that cause any issues?

Hello @DatNguyen 

Please refer AN11740 to debug the antenna, like the chapter 4.5, there is the answer to your question.
