CC2640: Tolerance of PWM from General Purpose Timer 2

Swarna Narayanan

Part Number: CC2640

Hi,

For my application, I am generating a PWM signal of 1.024MHz from GPT2 (General purpose timer 2) peripheral to be fed as an external clock to another sensor. How can I calculate the accuracy in ppm or % of this clock signal?

Hi Swarna,

The accuracy will be the same as your clock source. If you are using a crystal oscillator it will be around 20 ppm in room temp (depending the actual crystal used).

Regards,
Fredrik
