TIMING DIAGRAM
See AN-835, Understanding High Speed ADC Testing and Evaluation, for a complete set of definitions.
Output propagation delay is measured from CLK 50% transition to DATA 50% transition, with 5 pF load.
Wake-up time is dependent on the value of the decoupling capacitors, values shown with 0.1 μF capacitor across REFT and REFB.
See Figure 57 and the Serial Port Interface (SPI) section.
