CPHIZ: Charge Pump Hi-Z
Set the charge pump state to Hi-Z.
0: Normal
1: Hi-Z (Prohibited)
Be sure to set CPHIZ bit = “0”.
D[5]
CPPOLA: Charge pump output polarity
Set the charge pump output polarity.
0: Negative (Prohibited)
1: Positive
Be sure to set CPPOLA bit = “1”.
D[3:2]
MODE[1:0]: Local operation mode
Set the operation of Synthesizer, VCO, LOP and LON pins.
MODE[1:0] Local Operating MODE
0
Internal Synthesizer and VCO are activated.
1
Internal Synthesizer and VCO are activated and the local
signal is output from LOP and LON pins.
2
Internal VCO is inactivated. External VCO can be used with
internal synthesizer.
3
Internal Synthesizer and VCO are inactivated. External local
signal can be used.
Synthesizer setting frequency is output from LOP and LON pins when MODE[1:0] bits = “1”.
Refer to “8.2.2 Frequency Settings” for details.
The double carrier frequency of RFOUT should be input from LOP and LON pins when
MODE[1:0] bits = “3”.
