Figure 5. XCO Tuning
The typical start up time for the crystal oscillator (default
XCO_tune=13) is ~750us. If more capacitance is added
(higher XCO_tune value), then the start-up time will be
longer.
To save current in the crystal oscillator start-up period, the
XCO is turned on before any other circuit block. When the
XCO has settled, rest of the circuit will be turned on. No
programming should be made during this period.
The current consumption during the prestart period is
approximately 280A.

VCO_IB2 VCO_IB1 VCO_IB0 VCO_freq1 VCO_freq0
The VCO has no external components. It has three bit to
set the bias current and two bit to set the VCO frequency.
These five bits are set by the RF frequency, as follows:

Table 7. VCO Bit Setting
The bias bit will optimize the phase noise, and the
frequency bit will control a capacitor bank in the VCO. The
tuning range the RF frequency versus varactor voltage is
dependent on the VCO frequency setting, and can be
shown in Figure 6.

A lock detector can be enabled by setting LD_en = 1.
When pin LD is high, it indicates that the PLL is in lock.
When entering TX, the procedure is first to load the TX
word and then turn on the PA stage. During the PA ramp
up time, the LD signal may indicate out of lock. It is first
when the PA stage is fully on that the LD signal will
indicate in “Lock”. During transmission, the Lock Detect
signal will have transitions and the user should therefore,
ignore the Lock detect signal.
