Data Sheet
Two output clocks are provided to assist in capturing data from
the AD9212. The DCO is used to clock the output data and is
equal to five times the sample clock (CLK) rate. Data is clocked
out of the AD9212 and must be captured on the rising and

falling edges of the DCO that supports double data rate (DDR)
capturing. The FCO is used to signal the start of a new output
byte and is equal to the sample clock rate. See the timing
diagram shown in Figure 2 for more information.
