Datasheet - D e t a i l e d D e s c r i p t i o n
The comparator of the data slicer can work only with positive or with symmetrical threshold R3<6> . In addition the threshold can be 20 or 40 mV
R3<7> . In case the length of the preamble is an issue the data slicer can also work with an absolute threshold R1<7> . In this case the bits
R3<2:0> would not influence the performance. It is even possible to reduce the absolute threshold in case the environment is not particularly
noisy R2<7> .
8.5 Correlator
After frequency detection, the data correlation is only performed if the correlator is enabled ( R1<1> =1).
The data correlation consists of checking the presence of a preamble (ON/OFF modulated carrier) followed by a certain pattern.
After the frequency detection the correlator waits 16 bits (see bit rate definition in Table 19 ) and if no preamble is detected the chip is set back to
listening mode and the false-wake-up register ( R13<7:0> ) is incremented by one.
To get started with the pattern correlation the correlator needs to detect at least 4 bits of the preamble (ON/OFF modulated carrier).
The bit duration is defined in the register R7<4:0> (seeTable19)asfunctionoftheRealTimeClock(RTC)periods.
