Table 14. R0A: VAS CONFIG Register—VCO Autoselect Configuration (Address: 0Ah)
BIT NAME
BIT LOCATION
(0 = LSB)
TYPICAL
SETTING
FUNCTION
Sets the low-frequency clock divider.
00 = Use for 16MHz P f REF < 20MHz
LFDIV[1:0]
7:6
00
01 = Use for 20MHz P f REF < 28MHz
10 = Use for 28MHz P f REF P 32MHz
11 = Unused
Controls the VCO autoselect (VAS) start conditions function.
VASS
5
0
0 = VAS starts from the current VCO/VCOSB loaded in the VCO[1:0] and VSUB[3:0]
bits (in R00)
1 = VAS starts from the currently used VCO and VCOSB
VAS
4
1
Controls the VCO autoselect (VAS) function. Must set to 1 for proper operation.
Enables or disables the VCO tuning voltage ADC latch when the VCO autoselect
ADL
3
0
(VAS) mode is disabled.
0 = Disables the ADC latch
1 = Latches the ADC value
Enables or disables VCO tuning voltage ADC read when the VCO autoselect (VAS)
ADE
2
0
mode is disabled.
0 = Disables ADC read
1 = Enables ADC read
LTC[1:0]
1:0
10
Sets the VCO autoselect wait time. Must set to 10 for proper operation.
Note: Only production tested and guaranteed functional in states 0001 0010, 0101 0010, and 1001 0010. All other states are
untested and may not function correctly. Contact Maxim if untested settings will be used in production.
Table 15. R0B: PWRDET CFG1 Register—Power-Detector Configuration 1 of 2 (Address: 0Bh)
BIT NAME
BIT LOCATION
(0 = LSB)
TYPICAL
SETTING
FUNCTION
Enables or disables wideband power detector.
DWPD
7
0
0 = Enables wideband power detector. Use this state for autonomous RFAGC.
1 = Disables wideband power detector
Sets the wideband power-detector attack point (takeover point).
WPDA[2:0]
6:4
100
000 = Min
100 = Nom (see the Typical Operating Characteristics )
111 = Max
Enables or disables narrowband power detector.
DNPD
3
0
0 = Enables narrowband detector. Use this state for autonomous RFAGC.
1 = Disables narrowband detector
Sets the narrowband power-detector attack point (takeover point).
NPDA[2:0]
2:0
011
000 = Min
011 = Nom (see the Typical Operating Characteristics )
111 = Max
Note: Only production tested and guaranteed functional in state X100 X011, where X can be either 0 or 1. All other states are
untested and may not function correctly. Contact Maxim if untested settings will be used in production.
