MC33591 Technical Data

Note 3:
Sensitivity measurement method with Data Manager disabled (DME=0)
A continuous Manchester coded 0 sequence (4.8kBd, OOK modulation depth: 100%, FSK modulation
deviation: 35kHz, 50% duty cycle) is applied at RFIN. The mean value of the frequency of the output signal on
MOSI is measured over 200 cycles. The sensitivity is defined as the lowest input level during an NRZ one
corresponding to a mean output frequency deviation lower than 5% of the expected data rate.
Note 4:
Sensitivity measurement method with Data Manager enabled (DME=1, HE=0)
A complete telegram (4.8kBd, OOK modulation depth: 100%, FSK modulation deviation: 35kHz, 50% duty
cycle) including preamble, ID word and data (80 random bits without Header) is applied at RFIN. The sensitivity
is defined as the lowest input level during an NRZ one necessary to achieve 0 Bit Error Rate (BER).
Note 5:
50 matching networks
434MHz band: C1=1.5pF, C2=100pF, L1=68nH.
Tolerances: +/-10% for capacitances; +/-2% for inductor
Note 6:
Sensitivity measurement conditions
* OOK & FSK Modulation (+/-35kHz) at 4.8kBd (50% duty cycle)
* 315MHz & 434MHz bands (500kHz IF bandwidth)
* Performances include receiver crystal tolerance of +/-80ppm over temperature range i.e. +/-35kHz @
434MHz
Note 7:
FSK variation measurement conditions
A frequency modulated signal, carrier = 660kHz with ±35kHz deviation is injected at MIXOUT
Measure the DMDAT voltage swing at 660kHz, this will be DMDAT(Ref) in actual temperature/Vcc conditions
Measure the DMDAT voltage swing from Freq[1] = 660kHz - 120kHz to Freq[2] = 660kHz + 120kHz
DMDAT(Ref) / DMDAT(Freq[x]) is measured over the whole range Freq[1] to Freq[2]
