–30 SPI input/output data timing
The FPGA can be used to configure the desired conversion channel of the next transmission by
serializing an 8-bit configure data to ADC through the SDI signal. In this demonstration, SGL is set
to zero to specify differential conversion, and ODD/SIGN is set to zero to specify IN+ as EVEN
channel.
The FPGA retrieves the conversion result from the serialized data through the SDO pin. Note the
conversion data is for the target channel specified by previous configuration. When ADC is
powered on, the default selection used for the first conversion is IN+ = CH0 and IN– = CH1
(Address = 00000).
