0 shuts down the IF PLL. This mode is used with an external IF PLL.
0 shuts down the RF PLL. This mode is used with an external RF PLL.
0 for normal operation, 1 turns off the bias current to RFH0 output driver.
1 selects 200mV
1 selects ÷2 on IFLO port; 0 bypasses the divider.
1 bypasses IF VCO and enables a buffered input for external VCO use.
A 2-bit register sets the IF charge-pump current as follows:
00 = 139µA
01 = 192µA
10 = 278µA
11 = 390µA
A 2-bit register sets the RF charge-pump current as follows:
00 = 325µA
01 = 650µA
10 = 738µA
11 = 1063µA
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).
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 activates turbocharge feature, providing an additional IF charge-pump cur-
rent during frequency acquisition.
Works in conjunction with RCP_TURBO1 (OPCTRL register) to set the turbo-
charge current mode. (See Table 7).
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
RMS
input mode; 0 selects 100mV
