Power-On Initialization and Calibration Sequence
When the AD9807/AD9805 is powered on, the following
sequence should be used to initialize the part to a known state.
T he digital gain and offset buses are disabled until the calibra-
tion sequence. T he Bayer mode register must be written to and
set to zero if this mode is not going to be used.
