TDA 5211
Wireless Components
Specification, May 2001
This offset voltage is generated by the bias current of the negative input of the
comparator (i.e. 20nA) running over the external resistor R. This voltage raises
the voltage appearing at pin 20 (e.g. 1mV with R = 100k
). In order to obtain
benefit of this asymmetrical offset for the demodulation of long zeros the lower
of the two FSK frequencies should be chosen in the transmitter as the zero-
symbol frequency.
In the following figure the shape of the above mentioned bandpass is shown.

Frequency characterstic in case of FSK mode
The cutoff frequencies are calculated with the following formulas:
f

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