|
tone. If DDS_PHASE_DW is greater than 16(from REG_CHAN_CNTRL_1), the phase init
|
|
for tone 2 is extended in REG_CHAN_CNTRL_10. NOT-APPLICABLE if DDS_DISABLE is
|
|
set (0x1).

Sets the frequency of the phase accumulator. Its value can be calculated by

<m>INCR = (f_out * 2^16) * clkratio / f_if</m>; where f_out is the generated
|
|
output frequency, and f_if is the frequency of the digital interface, and
|
|
clock_ratio is the ratio between the sampling clock and the interface clock.
|

If DDS_PHASE_DW is greater than 16(from REG_CHAN_CNTRL_1), the phase increment
|
|
for tone 2 is extended in REG_CHAN_CNTRL_10. NOT-APPLICABLE if DDS_DISABLE is

set (0x1).
