Tolerances and start-up times will depend on the crystal used. Depending on the RF frequency and channel spacing the IC must be
calibrated to the exact crystal frequency using the readings of the register TRKFREQ
External clock should be input via an AC coupling at pin CLK16P with the oscillator powered up
