FSK Demodulator:
The FSK Demodulator is based on a delay and multiply principle (DAM). The required
settings are the DAM delay, the decimation factor (IDDEC) of the data filter and a final
scaling (ID scaling).
ID decimation:
IDDEC...Integrate and Dump decimation
RFSKCIC...Decimation Factor FSK CIC Filter(=FSKFILBW0+1)
RDatafilter...Decimation Factor Data filter(=DATFILT1+1)

ID scaling:
IDSCA...Integrate and Dump scaling
IDDEC...Integrate and Dump decimation(=FSKDEMBW1)
The calculations above are fully automatically performed by the IAF TDA523x
Configuration Tool!
