We are trying to load AD9781 registers via SPI. We are stuck at determining the SET, HLD and SMP delay. The table generation mentioned in datasheet is too tedious, and takes too much time. Are there any standard value for 200MSPS clock?
Regarding setting full scale current - To set 20mA output current, Register 0X0B should be "0X00" and Register 0X0C should be "0X02", isnt it? We are having doubts regarding MSB and LSB values of this Full Scale adjustment register.
We do have parts AD9717 that can be programmed down to 1ma full scale but AD9781 minimum full scale curren is 8.66ma as specified in the data sheet.
