Q
Should I connect to ground the CMLI, CMLQ, FSADJI and FSADJQ pins?I'm setting the following AD9716 registers with the following values?
Reg Bin Hex
0x04 10000000 80
0x05 00000000 00
0x07 10000000 80
0x08 00000000 00

From your register settings IRseten=1, QRseten=1 and IRcmlen=QRcmlen=0. Thismeans:
CMLI and CMLQ should be connected to AVss via a 0ohm resistor.
FSADJQ and FSADJI are set as the outputs of the Auxillary DACs. Then you will
need to set the AUXDACQ, AUXDACI, AUXCTLQ, and AUXCTLI registers accordingly.
More on the Auxillary DACs can be found on page 49 of the datasheet:
