The quads are made equal to 8 in the system estimator just for the purpose of computing the correct power requirements. De-aliasing uses 2 frames with different frequencies in Calculus. Therefore, for the purpose of power calculations it is equivalent to using double the number of quads. But this is simplistic assumption as the number of sub-frames can be different for the two frames.

For understanding how the configuration needs to be set, please refer to attached datasheet (7.3.4.2.1 Procedure for Enabling De-Aliasing Mode).
