CC1352P: Offset about 27KHz

Hi Ti!

Is an offset at the 27KHz RF frequency a large deviation or could it be considered acceptable?

Thanks very much

    Hi,

    Are you measuring this on the 2.4 GHz port or on the sub-1 port ?

    If your are measuring this at 2.440 GHz, then the offset is 11.1 ppm but if you are measuring this at 868 MHz, then the offset is 31.1 ppm.

    The frequency offset should not exceed the maximum crystal offset of the crystal in ppm.
