Timing Chart
Figure 2 shows the timing chart when CDSIN and ADCIN input modes are used.
• The ADC output (D0 to D9) is output at the rising edge of the ADCLK in both modes.
• Pipe-line delay is ten clock cycles when CDSIN is used and nine when ADCIN is used.
• In ADCIN input mode, the input signal is sampled at the rising edge of the ADCLK.
