OUTPUT PHASING
The relative phases of the analogue outputs will depend upon the following factors:
1.
2.
3.
Figure 32 shows where these phase inversions can occur in the output signal path.
DACLPOL and DACRPOL invert bits: Setting these bits to 1 will invert the DAC output.
Mixer configuration: The polarity of the signal will depend upon the route through the mixer path.
For example, DACL can be directly input to the OUT3 mixer, giving a 180° phase shift at the
OUT3 mixer output. However, if DACL is input to the OUT3 mixer via the left mixer, an
additional phase shift will be introduced, giving 0° phase shift at the OUT3 mixer output.
Output boost set-up: When 1.5x boost is enabled on an output, no phase shift occurs. When
1.5x boost is not enabled, a 180° phase shift occurs.
