Description
Bit synchronizer
0 -> disabled
1 -> enabled
BARKER coder/decoder:
0 -> disabled
1 -> enabled
RSSI function:
0 -> disabled
1 -> enabled
RSSI range:
0 -> low range (see 3.2.2)
1 -> high range (see 3.2.2)
FEI function:
0 -> disabled
1-> enabled
Baseband filter bandwidth (BBW)
0 -> 200 kHz (DSB)
1 -> 600 kHz (DSB)
Reference frequency source:
0 -> internal crystal oscillator
1 -> external source
CLKOUT - Reference frequency divided by 4,8,16,or 32:
0 -> disabled
1 -> enabled
Transmitter pre-filter rise/fall time:
0 -> 10% of bit duration
1 -> 20% of bit duration
Pre-filtering of the bit stream in transmitter mode
0 -> no filtering
1 -> filtering
The filtering function is available only for the following bit rates
and frequency deviations:
FSPanam_Br = "1111110" -> BR = 1200 bit/s
FSPanam_Br = "0111111" -> BR = 2400 bit/s
FSPanam_Br = "0011111" -> BR = 4800 bit/s
FSPanam_Br = "0001111" -> BR = 9600 bit/s
FSPanam_Br = "0000111" -> BR = 19200 bit/s
FSPanam_Br = "0000011" -> BR = 38400 bit/s
FSPanam_Br = "0000001" -> BR = 76800 bit/s
FSParam_Dev = "00101000" -> Δf = 40 kHz
FSParam_Dev = "00110111" -> Δf = 55 kHz
FSParam_Dev = "01010000" -> Δf = 80 kHz
FSParam_Dev = "10100000" -> Δf = 160 kHz
FSParam_Dev = "11001000" -> Δf = 200 kHz
Transmitter modulation:
0 -> enabled
1 -> disabled
