TIMING
The AD9609 provides latched data with a pipeline delay of
eight clock cycles. Data outputs are available one propagation
delay (tPD) after the rising edge of the clock signal.
Minimize the length of the output data lines and loads placed
on them to reduce transients within the AD9609. These
transients can degrade converter dynamic performance.
The lowest typical conversion rate of the AD9609 is 3 MSPS. At
clock rates below 3 MSPS, dynamic performance can degrade.
Data Clock Output (DCO)
The AD9609 provides a data clock output (DCO) signal
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.
