Example:
R = 100k Ω
C = 47nF
This leads to f
and
ASK Mode
In case the receiver is operated in ASK mode the datapath frequency charac-
tersitic is dominated by the data filter alone, thus it is lowpass shaped.The cutoff
frequency is determined by the external capacitors C12 and C14 and the inter-
nal 100k resistors as described in Section 4.2
Figure 4-9

is the 3dB cutoff frequency of the data filter - see Section 4.2.
