The format of the output data is offset binary by default. An
example of the output coding format can be found in Table 9.
To change the output data format to twos complement, see the
Memory Map section.

Data from each ADC is serialized and provided on a separate
channel. The data rate for each serial stream is equal to 12 bits
times the sample clock rate, with a maximum of 600 Mbps
(12 bits × 50 MSPS = 600 Mbps). The lowest typical conversion
rate is 10 MSPS, but the PLL can be set up for encode rates as
low as 5 MSPS via the SPI if lower sample rates are required for
a specific application. See the Memory Map section for details
on enabling this feature.
Two output clocks are provided to assist in capturing data from
the AD9271. DCO± is used to clock the output data and is equal
to six times the sampling clock rate. Data is clocked out of the
AD9271 and must be captured on the rising and falling edges of
the DCO± that supports double data rate (DDR) capturing. The
frame clock output (FCO±) is used to signal the start of a new
output byte and is equal to the sampling clock rate. See the
timing diagram shown in Figure 2 for more information.
