DEM_OUT Output
RSSI Output
If a disturbing signal falls into the received band or a blocker is not continuous wave, the perfor-
mance of a receiver strongly depends on the circuits after the IF filter. The demodulator, data
filter and data slicer are important, in that case.
The data filter of the ATA5423/ATA5425/ATA5428/ATA5429 implies a quasi-peak detector. This
results in a good suppression of the above mentioned disturbers and exhibits a good carrier to
Gaussian noise performance. The required useful signal to disturbing signal ratio to be received
with a BER of 10
BR_Range_2)/6 dB (BR_Range_3) in FSK mode. Due to the many different waveforms possible
these numbers are measured for signal as well as for disturbers with peak amplitude values.
Note that these values are worst case values and are valid for any type of modulation and mod-
ulating frequency of the disturbing signal as well as the receiving signal. For many combinations,
lower carrier to disturbing signal ratios are needed.
The internal raw output signal of the demodulator Demod_Out is available at pin DEM_OUT.
DEM_OUT is an open drain output and must be connected to a pull-up resistor if it is used (typi-
cally 100 k ) otherwise no signal is present at that pin.
The output voltage of the pin RSSI is an analog voltage, proportional to the input power level.
Using the RSSI output signal, the signal strength of different transmitters can be distinguished.
The usable dynamic range of the RSSI amplifier is 70 dB, the input power range P(RF
–115 dBm to –45 dBm and the gain is 8 mV/dB.
