The amplifier power stage of the uses a built in oscillator that can be trimmed by an external resistor from the FREQ_ADJ pin to GND. Changes in the oscillator frequency should be made with resistor values specified in Recommended Operating Conditions while RESET is low. See section DAC and DSP Clocking for configuring the clocks for the digital front-end (DAC and DSP).
To reduce interference problems while using a radio receiver tuned within the AM band, the switching frequency can be changed from nominal to lower or higher values. These values should be chosen such that the nominal and the alternate switching frequencies together result in the fewest cases of interference throughout the AM band. The oscillator frequency can be selected by the value of the FREQ_ADJ resistor connected to GND in master mode.
