RE: nRF54L15 reference design: are ±0.05 pF tolerances necessary?

Hello Jonathan,

The specification are for the components we have used to characterise and qualify our chip. You can choose to go differently. The outcome would be that the performance between boards will have larger variations. You can choose to do this, but the RF performance might be more uneven between boards you build. If that's something you are ok with, then that is fine. We recommend anyway to do some validation on your own as well with the components you source and use.

I'd say if you are planning on using the full +8dBm output power, you will probably want to stick with the stricter tolerances as the attenuation of harmonics becomes more predictable. If you are not using the full +8dBm, the lower tolerance +/-0.1pF would be less challenging.

Best regards

Asbjørn
