The input stage takes as an input N=4 or N=8 input words at T4/T8 clock rate and output a single sample per T4/T8 cycle. The block operates in one of two modes below:
- Averaged mode
- An averaged amplitude of all sub-ADCs input is used to detect the signal amplitude.
- Random Sampling
- A single randomly selected data word (sub ADC) is used to detect the signal magnitude.
