VCO and PLL Self-Calibration
VCO
The VCO is completely integrated and
operates at 4800 – 4966 MHz. The VCO
frequency is divided by 2 to generate
frequencies in the desired band (2400-
2483.5 MHz).
PLL self-calibration
The VCO's characteristics will vary with
temperature, changes in supply voltages,
and the desired operating frequency.
In order to ensure reliable operation the
VCO’s bias current and tuning range are
automatically calibrated every time the RX
mode or TX mode is enabled, i.e. in the
RX_CALIBRATE, TX_CALIBRATE and
TX_ACK_CALIBRATE control states in
Figure 24 on page 43.
Output Power Programming
The RF output power of the device is
programmable and is controlled by the
TXCTRL.PA_LEVEL
register. Table 9
shows the output power for different
settings,
programming of the
TXCTRL
control
register. The typical current consumption
is also shown.

Voltage Regulator
CC2420
includes a low drop-out voltage
regulator. This is used to provide a 1.8 V
power supply to the
CC2420
power
supplies. The voltage regulator should not
be used to provide power to other circuits
because
of
limited
capability and noise considerations.
power
sourcing
The voltage regulator input pin
VREG_IN
is connected to the unregulated 2.1 to 3.6
V power supply. The voltage regulator is
enabled / disabled using the active high
voltage regulator enable pin
VREG_EN
.
The regulated 1.8 V voltage output is
available on the
VREG_OUT
pin. A

regulator is shown in Figure 27.

When disabling the voltage regulator, note
that register and RAM programming will
be lost as leakage current reduces the
