In AD9643 datasheet the Test mode register 0x0D bits 7 and 6 are defined as Bit 7 = User test mode control 0 = continuous/ repeat pattern 1 = single pattern, then 0s and Bit 6 =Open.
- But in the Application note AN877 page 11 it is given that Bits 7 and 6 are used for sequencing the user pattern. So is the same true for this AD9643 also?
- In AD9643 there are 4 user test patterns so how the remaining two are selected.
- Is it something like two of the user test patterns are for I channel output and the remaining two are for Q channel ?
