The chapter of "AD5310R SPI SERIAL DATA INTERFACE" of the data sheet is as follows.
"The SYNC pin must be held low until the complete data-word (16 bits) is loaded from the SDI pin, as shown in Figure 3.
However, I think Figure 3. (and Figure 40) show a 24-bit data stream.
Is the input data stream for the AD5310R correct at 16 bits long?
Best regards
