I am currently testing the adi_adrv9025_FramerTestDataSet api, using injectPoint = FRAMERINPUT.
I have tested the possible sources:
CHECKERBOARD seems to work fine getting I=Q=0b1010 1010 1010 1010
TOGGLE0_1 works too, getting I=Q=0, then I=Q=-32768, etc.
But PRBS23 gives only 0, PRBS9 too. Is it normal ?
PRBS7 give data, but data have more than 7bits, so it seems wrong.
What should give RAMP ? I am getting I(n) = Q(n) = I(n-1)+256=Q(n-1)+256
Is it expected ? there is no documentation about this.
