I have a midterm coming up and just wanting to confirm if these answers make sense

The Maxim MAX11100 16-bit successive approximation ADC is rated for a maximum clock frequency of 4.8MHz and requires 8 clock cycles for sample and hold acquisition time.

a. What is the minimum conversion time for the ADC?

Is the conversion time just (1/4.8 MHz)* 8 = 1.67 us?

b. We wish to sample a signal with a maximum frequency component of 90 kHz. Could we successfully sample the signal without aliasing using the MAX11100? Be sure to justify your answer.

Now what im not too sure if i should consider the maximum clock frequency as the sampling frequency? therefore the ADC should easily sample the signal without aliasing since the nyquist theorem just states that the sampling frequency should be at least twice as much as the input's maximum frequency component

Thanks for the input.
