ADC Clock

Other Parts Discussed in Thread: CONTROLSUITE

Hey, guys

I am working on ADC of F28069 microcontroller. I have seen many ADC examples online and from ControlSuite, and all of them shows that ADCCLK = SYSCLK/2. Also, the data sheet of the microcontroller shows that the conversion time is 289ns (13 ADC clock cycles), it also based on the assumption that ADCCLK = SYSCLK/2. I was wondering whether the fastest ADC clock has to be half of system clock, or it can also equals to system clock. Thank you guys in advance.
