The selection is done with the registers FSKFILBW0 and FSKFILBW1.
1) Values are only ”about” values and should be used for orientation only. Bandwidth is also dependent on
THe CIC-Filter also requires a comb delay and a scaling. For the comb delay, a value of
8 must be used.
The scaling is calculated as below:
SCA... Scaling
R...Decimation Factor(=FSKFILBW0+1)
M...Comb Delay Value(=8 +1= 9)
The calculation above is fully automatically performed by the IAF TDA523x
