NOTE:
8.The filter specification is based on a 10.24 MHz 2nd LO, and a switch–capacitor (SC) filter counter divider ratio of 31. If other 2nd LO frequencies
and/or SC filter counter divider ratios are used, the filter corner frequency will be proportional to the resulting SC filter clock frequency.
