Enable lock detector circuitry
Modify lock range for lock detector
VCO warm-up time=TVCO/(F
Phase detector polarity: 0=positive, 1=negative
Active loop filter enable, 1=Active 0=Passive
Charge pump leakage current: 00=no leakage, 01=low leakage, 10=mid leakage, 11=high
leakage
Polarity of VCO coarse-tune word: 0=positive, 1=negative
0=Normal operation 1=external VCO (VCO3 disabled, KV_CAL and CT_CAL must be dis-
abled)
0=Half duplex, mixer is enabled according to MODE pin, 1=Full duplex, both mixers enabled
0=High charge pump current, 1=low charge pump current
