Analog to Digital Converter
ADCs are nominally operating at 20 Msamples/s. The input
range of the ADC is between 0.75 and 1.75V. The analog
input signal is sampled at 2.1 ns delay from the rising edge
of the ADC clock.

moment. The data is delayed by 3.7 ns with respect to this
falling edge. This is illustrated in Figure 6.
