The format of the output data is offset binary by default. An
example of the output coding format can be found in Table 8.
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 10 bits
times the sample clock rate, with a maximum of 650 Mbps
(10 bits × 65 MSPS = 650 Mbps). The lowest typical conversion
rate is 10 MSPS. However, if lower sample rates are required for
a specific application, the PLL can be set up via the SPI to allow
encode rates as low as 5 MSPS. See the Memory Map section for
information about enabling this feature.
