nRF24L01+ XC1 driving by MCU PWM

[summoner45]

Hello. I'm using 24 MHz crystal to feed my MCU and not able to change it to 16 MHz to share with nrf24. Now I'm driving nrf24 XC1 with PWM signal 16 MHz and it works but not stable. Can i get any advice how to improve stability. http://clip2net.com/s/3jz3xFD clock characteristics table like this could help.

Hi,

The 16M clock source needed by the nRF24L01+ has to be within the parameters given in chapter 5.5 in the nRF24L01+ datasheet.

The frequency shall be 16.000 MHz, with a tolerance of max. +/- 60 ppm.

The signal shall be fed into pin "XC1" when driven from an external source.

Have you made sure that all of the above criterias has been satisfied?

Cheers, Håkon
