AD9233
TIMING
The lowest typical conversion rate of the AD9233 is 10 MSPS. At clock rates below 10 MSPS, dynamic performance can degrade.
The AD9233 provides latched data outputs with a pipeline delay of 12 clock cycles. Data outputs are available one propagation delay (tPD) after the rising edge of the clock signal.
The length of the output data lines and the loads placed on them should be minimized to reduce transients within the AD9233. These transients can degrade the dynamic performance of the converter.
Data Clock Output (DCO)
The AD9233 provides a data clock output (DCO) intended for capturing the data in an external register. The 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.
