For the AD9262BCPZ-5 and the AD9262BCPZ, typical values double and quadruple the number of cycles, respectively. 4 Cycles refers to modulator clock cycles. 5 Wake-up time is dependent on the value of the decoupling capacitor, value shown with 10uF capacitor on VREF and CFILT. 6 See Figure 60 and the Serial Port Interface (SPI) section.
