Hello, everybody. I found the AD9102 very useful chip. But I have a question about SPI interface.
In the documentation I found "In 4-wire SPI mode (SDO), this pin outputs the data from the SPI." I assume the AD9102 is slave.
But in the figure "Figure 33. Serial Register Interface Timing, MSB First Read, 4-Wire SPI" it seems that SDO is idle in Read mode.
Can it be true?
And why in the Write mode (figure. 33) there is a data on SDO? Does the AD9102 send the data out in write cycle?
Sorry, maybe I missed some information, but it seems to me it's a mistake or something?
Thank you if you have a time to reply to me.
