Description
Power Down
0 = Chip Enable
1 = Chip Disable (only reference oscillator core on)
Receive/Transmit-mode control
0 = Receive mode
1 = Transmit mode
Synthesiser test modes (apply when TDEM2=0)
Modus (000):
Normal operation: Rx/Tx.
Modus (001):
Divided signal from VCO at PD input monitored at LOCK pin.
Modulation (control of A-counter) is disabled.
Modus (010):
Divided signal from VCO at PD input monitored at LOCK pin.
Modulation (control of A-counter) is enabled.
Modus (011):
Output from reference divider monitored at LOCK pin.
Modus (100):
Signal at TX_DATA pin used as modulation control overriding
the signal from the dual-modulus divider. Output monitored at
LOCK pin.
Modus (101):
Output from prescaler monitored at LOCK pin.
Modulation (A-divider control) disabled.
Modus (110):
Output from prescaler monitored at LOCK pin.
Modulation (A-divider control) disabled.
Modus (111):
Shift register data output monitored at LOCK pin.
PA gain programming. Part of PA4:PA0. (PA1:PA0 is in frame
D, PA4 is in frame C)
LNA bias current and gain
00 = 0.94mA=I
01 = 1.5* I
10 = 2* I
11 = 3* I
MIXER bias current and gain
00 = 0.36mA
01 = 0.54mA
10 = 0.72mA (nominal setting)
11 = 1.08mA
LO drive (peak-differential = peak-peak single-ended)
00 = 144mV
01 = 288mV
10 = 432mV (nominal setting)
11 = 720mV
