CROSS CONTROLLER REGISTERS
The AD973x differential output stage is adjustable to equalize
the charge injection into the positive and negative outputs. This
adjustment impacts certain performance characteristics, such as
harmonic distortion or IMD. System performance can be en-
hanced by adjusting the cross controller.
If the system is calibrated after manufacture, adjust the cross
controller offsets to provide optimum performance. To start,
increment DNDEL<5:0> (Reg. 11, Bits 5:0) while observing
HD2 (second harmonic distortion) and/or IMD to find the
desired optimum. If DNDEL does not influence the perform-
ance, set it to 0 and increment UPDEL<5:0> (Reg. 10, Bits 5:0).
Based on system characterization, set one of these controls to
the maximum value to yield the best performance.
Figure 85 shows the effect of UPDEL and DNDEL.
