Two output clocks are provided to assist in capturing data from
the AD9228. The DCO is used to clock the output data and is
equal to six times the sample clock (CLK) rate. Data is clocked
out of the AD9228 and must be captured on the rising and
falling edges of the DCO that supports double data rate (DDR)

byte and is equal to the sample clock rate. See the timing
diagram shown in Figure 2 for more information.
