TIMING
The lowest typical conversion rate of the AD9246 is 10 MSPS.
At clock rates below 10 MSPS, dynamic performance can degrade.
The AD9246 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
AD9246. These transients can degrade the dynamic performance
of the converter.
Data Clock Output (DCO)
The AD9246 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.
