Tolerance recommendation for South Korea and PN5180

[marcinbaliniak]

Hi,

We are developing RFID device using your chip PN5180. We are going to sell this device in South Korea. We know that we need 10ppm tolerance for main frequency. Do you have any suggestions about recommended crystal, layout, capacitors etc. to match these tight limits and pass certification required in this country?

Thank in advance,

Marcin.

Hello,

Please accept my apologies but we are not familiar with the regulations there, but please let me share the crystal used in our evaluation board for your reference:

Also, please refer to the antenna design guide for hardware design recommendations:

Hope it helps!
