FSTST3 (0x2A) - Frequency Synthesizer Test Register 3
Bit
Field Name
Reset
R/W
Description
15
CHP_CAL_DISABLE
1
R/W
Disable charge pump during VCO calibration when set.
14
CHP_CURRENT_OE
0
R/W
Charge pump current override enable
0 : Charge pump current set by calibration
1 : Charge pump current set by START_CHP_CURRENT
13
CHP_TEST_UP
0
R/W
Forces the CHP to output "up" current when set
12
CHP_TEST_DN
0
R/W
Forces the CHP to output "down" current when set
11
CHP_DISABLE
0
R/W
Set to manually disable charge pump by masking the up and
down pulses from the phase-detector.
10
PD_DELAY
0
R/W
Selects short or long reset delay in phase detector:
0: Short reset delay
1: Long reset delay
9:8
CHP_STEP_PERIOD[1:0]
2
R/W
The charge pump current value step period:
0: 0.25 us
1: 0.5 us
2: 1 us
3: 4 us
7:4
STOP_CHP_CURRENT[3:0]
13
R/W
The charge pump current to stop at after the current is stepped
down from START_CHP_CURRENT after VCO calibration is
complete. The current is stepped down periodically with intervals
as defined in CHP_STEP_PERIOD.
3:0
START_CHP_CURRENT[3:0]
13
R/W
The charge pump current to start with after VCO calibration is
complete. The current is then stepped down periodically to the
value STOP_CHP_CURRENT with intervals as defined in
CHP_STEP_PERIOD.
Also used for overriding the charge pump current when
CHP_CURRENT_OE=’1’
