I am having significant spurious emissions in the 790 MHz - 798 MHz range while operating the CC1121 in the 902 MHz - 928 MHz range. The circuit uses a 32 MHz crystal. The datasheet mentions that transmissions at frequencies within 1 MHz of a multiple of the crystal frequency should be evaluated for spurs. Are the 7xx MHz spurs related to this note? What is the relationship between the spur frequency and the transmission frequency?
