Description
Demodulator data filter topology
AC coupling by-pass
0 = Two AC couplings
1 = One AC coupling
Demodulator data slicer comparator hysteresis
00 = 0mV
01 = 15mV
10 = 40mV
11 = 100mV
Demodulator data filter high-pass cut-off
00 = 30Hz
01 = 60Hz
10 = 120Hz
11 = 240Hz
Demodulator external AC-coupling
0 = Internal
1 = Eksternal (NA)
IF test mode
IF signal input at TX_DATA pin
Use LOCK pin as demodulator output
0 = Normal
1 = Test mode
Quadrature detector output level
0 = VDD (normal setting)
1 = Reduced amplitude (VDD/2)
IF and demodulator Power Down (overrided by global power
down).
0 = IF and demodulator active (if PD=0 and RxTx=0). Normal
setting.
1 = IF and demodulator power down
