As shown in the block diagram, each of the sub-RF-ADCs are independently in separate data streams until they get mixed by the QMC block, complex mixer, and then filtered by the DDC. The OCB2, GCB, and TSCB coefficients are applied to each sub-RF-ADC independently and can be effectively disabled if you permanently sets the freeze port to active-High. If the QMC block and the DDC block (hence the mixer) are bypassed, then the sub-RF-ADC data streams are output to the logic independently.
