Description
PA “class”
00 = Class A
01 = Class AB
10 = Class B
11 = Class C
D-counter
Frequency seperation programming
Description
00 = External clock (25MHz) at TX_DATA.
01 = 12.8 MHz from crystal oscillator
10 = 25 MHz from prescaler
11 = 12.5MHz from prescaler
Demodulator phase shift / IF control
00 = 60kHz IF
01 = 200kHz IF
10 = 455kHz IF
11 = Test modes using DCLK1:DCLK0
Test modes for demodulator. Output is monitored at LOCK
pin. See also S2:S0 in frame A.
TDEM2=0: As described for S2:S0 in frame A
TDEM2=1 : Demodulator test modes.
Modus (000):
Normal setting.
Modus (0XX):
Test as for S2:S0 in frame A monitored at LOCK pin.
Modus (100):
Demodulator input monitored at LOCK pin.
Modus (101):
Phase shifted signal monitored at LOCK pin.
Modus (110):
Phase detector output monitored at LOCK pin.
Modus (111):
Demodulator output at LOCK pin. IF input at TX_DATA.
PA capacitor array.
Array is active in RX or TX depending on INVARRAY.
000 = 0pF
001 = 1.25pF
010 = 2.5pF
011 = 3.75pF
100 = 5pF
101 = 6.25pF
110 = 7.5pF
111 = 8.75pF
PA capacitor array activation.
0 = Capacitor array active in RX mode
1 = Capacitor array active in TX mode
PA buffer amplifier drive level
00 = 3mA
01 = 5mA
10 = 8mA
11 = 11mA
