The ADC digital block is clocked by the system clock and the ADC analog block is clocked from a separate conversion clock (ADC clock). The ADC clock frequency can be up to 32 MHz to generate a conversion rate of 2 Msps. A 16-MHz ADC clock provides a 1-Msps sampling rate. There are three sources for the ADC clock:
NOTE
If the ADC module is not using the PIOSC as the clock source, the system clock must be at least 16 MHz.
