REGISTER 5—IF FILTER SETUP REGISTER
•
•
A coarse IF filter calibration is performed when the
IF_CAL_COARSE bit (R5_DB4) is set. If the IF_FINE_
CAL bit (R6_DB4) has been previously set, a fine IF filter
calibration is automatically performed after the coarse
calibration.

IF_FILTER_ADJUST allows the IF fine filter calibration
result to be programmed directly on subsequent receiver
power-ups, thereby saving on the need to redo a fine filter
calibration in some instances. Refer to the Filter Bandwidth
Calibration Readback section for information about using
the IF_FILTER_ ADJUST bits.
R5_DB[20:31] are used for image rejection calibration. Refer
to the Image Rejection Calibration section for details on how
to program these parameters.
