Charge pump current switch during calibration.
0=Constant Current
1=Switches high during calibration
VT pin enable
0=Charge Pump/Internal Loop Filter are disconnected from VT pin
1=Charge Pump/Internal Loop Filter are connected to VT pin
Lock Detect Enable for PLL
VCO Coarse Tune Enable
0=VCO coarse tuning system is disabled
1=VCO coarse tuning system is enabled
KV Calibration Enable
0=disabled
1=enabled
Loop Filter Bandwidth Selector
0=External RX RF2722
1=Internal TX VCO’s
Loop 1 Filter Bypass
0=Internal Loop Filter is used
1 =Internal Loop Filter is bypassed
Charge Pump Leakage Current
0=minimum value
1=2*minimum value
Charge Pump Current
0=low current setting, used for RX with the RF2722
1=high current setting, used for TX with internal VCOs
Loop 1 Phase Detector Polarity
0=negative, VCO freq decreases with increasing tuning voltage, used for RX with
1=positive, VCO freq increases with increasing tuning voltage, used for TX with
Prescaler Modulus
The prescaler is set as follows:
0x=prescaler is bypassed, (0MHz to 500MHz at prescaler input)
10=4/5 Mode (494MHz to 2GHz at prescaler input)
11=8/9 Mode (1.95GHz to 2.5GHz at prescaler input)
VCO Select
00=external VCO, FIN pin is used as input
10=integrated VCO1
11=integrated VCO2
VCO Post Divider
0x=The VCO is directly coupled to the Prescaler.
10=The VCO is followed by a fixed divide by 2.
11=The VCO is followed by a fixed divide by 4. This setting is used with the
Program to zero (0).
