STATE
Determines output mode for LOCK detector pin as follows:
00 = test mode, LD_MODE cannot be 00 for normal operation
01 = IF PLL lock detector
10 = RF PLL lock detector
11 = logical AND of IF PLL and RF PLL lock detectors

LD_MODE
1 activates turbocharge feature, providing an additional 435μA of IF charge-
pump current during frequency acquisition.

1 activates turbocharge feature, providing an additional 450μA of IF charge-
pump current during frequency acquisition.

IF_TURBO_
CHARGE
RF phase-detector polarity; 1 selects positive polarity (increasing tuning voltage
on the VCO produces increasing frequency); 0 selects negative polarity
(increasing voltage on the VCO produces decreasing frequency).

1
RF_PD_POL
IF phase-detector polarity; 1 selects positive polarity (increasing tuning voltage
on the VCO produces increasing frequency); 0 selects negative polarity
(increasing tuning voltage on the VCO produces decreasing frequency).

A 2-bit register sets the RF charge-pump current as follows:
00 = 165μA
01 = 230μA
10 = 340μA
11 = 450μA
00

input mode; 0 selects 100mV
RMS
input mode.

IQ_LEVEL
1 selects ÷2 on IFLO port; 0 bypasses the divider.
0
BUF_DIV
1 bypasses IF VCO and enables a buffered input for external VCO use.
0
VCO_BYPASS
A 2-bit register sets the IF charge-pump current as follows:
00 = 175μA
01 = 235μA
10 = 350μA
11 = 465μA
00
ICP
Must be set to 0 for normal operation.
0
RESERVED
0 shuts down the BF PLL. This mode is used with an external RF PLL.
1
RF_PLL_
SHDN
0 shuts down the IF PLL. This mode is used with an external IF VCO and IF PLL.
