Register 6—VCO Control and Enables
With R6[2:0] set to 110, the VCO control and enables register is
programmed as shown in Figure 39.
VCO band selection is normally selected based on BANDCAL
calibration; however, the VCO band can be selected directly using
Register 6. The VCO BS SRC determines whether the BANDCAL
calibration determines the optimum VCO tuning band or if the
external SPI interface is used to select the VCO tuning band
based on the value of the VCO band select.
The VCO amplitude can be controlled through Register 6. The
VCO amplitude setting can be controlled between 0 and 31
decimal, with a default value of 24.
The internal VCO can be disabled using Register 6. The internal
VCO LDO can be disabled if an external clean 3.0 V supply is
available.
The internal charge pump can be disabled through Register 6.
Normally, the charge pump is enabled.
