Timing Chart
Figure 2 shows the timing chart when CDSIN and ADCIN input modes are used.
The ADC output (D0 to D11) is output at the rising edge of the ADCLK in both modes.
Pipe-line delay is twelve clock cycles when CDSIN is used and eleven when ADCIN is used.
In ADCIN input mode, the input signal is sampled at the rising edge of the ADCLK.
