APPENDIX A
DAC Timing Control Example
The AD73322L
’
s DAC is loaded from the DAC register con-
tents just before the ADC register contents are loaded to the
serial register (SDOFS going high). This default DAC load
position can be advanced in time to occur earlier with respect to
the SDOFS going high. Figure 45 shows an example of the
ADC unload and DAC load sequence. At time t
1
the SDOFS is
raised to indicate that a new ADC word is ready. Following the
SDOFS pulse, 16 bits of ADC data are clocked out on SDO in
the subsequent 16 SCLK cycles finishing at time t
2
where the
DSP
’
s SPORT will have received the 16-bit word. The DSP
may process this information and generate a DAC word to be
sent to the AD73322L. Time t
3
marks the beginning of the
sequence of sending the DAC word to the AD73322L. This
sequence ends at time t
4
where the DAC register will be updated
from the 16 bits in the AD73322L
’
s serial register. However,
the DAC will not be updated from the DAC register until time
t
5
, which may not be acceptable in certain applications. In order
to reduce this delay and load the DAC at time t
6
, the DAC
advance register can be programmed with a suitable setting
corresponding to the required time advance (refer to Table X
for details of DAC Timing Control settings).
