TIMING
The AD9266 provides latched data with a pipeline delay of
eight clock cycles. Data outputs are available one propagation
delay (t
Minimize the length of the output data lines and loads placed
on them to reduce transients within the AD9266. These
transients can degrade converter dynamic performance.

The lowest typical conversion rate of the AD9266 is 3 MSPS. At
clock rates below 3 MSPS, dynamic performance may degrade.
Data Clock Output (DCO)
The AD9266 provides a data clock output (DCO) signal that is
intended for capturing the data in an external register. The CMOS
data outputs are valid on the rising edge of DCO, unless the DCO
clock polarity has been changed via the SPI. See Figure 2 for
a graphical timing description.
