2.4.1 PLL Synthesizer
The Phase Locked Loop synthesizer consists of a Voltage Controlled Oscillator
(VCO), an asynchronous divider chain, a phase detector, a charge pump and a
loop filter. It is fully implemented on chip. The tuning circuit of the VCO consist-
ing of spiral inductors and varactor diodes is on chip, too. Therefore no addi-
tional external components are necessary. The nominal center frequency of the
VCO is 630 MHz. The oscillator signal is fed both, to the synthesizer divider
chain and to the power amplifier. The overall division ratio of the asynchronous
divider chain is 64. The phase detector is a Type IV PD with charge pump. The
passive loop filter is realized on chip.
2.4.2 Crystal Oscillator
The crystal oscillator operates at 9.84 MHz.
The crystal frequency is divided by 16. The resulting 615.2 kHz are available at
the clock output CLKOUT (pin1) to drive the clock input of a micro controller.
To achieve FSK transmission, the oscillator frequency can be detuned by a
fixed amount by switching an external capacitor via FSKOUT (pin 4).
The condition of the switch is controlled by the signal at FSKDTA (pin 7). Low:Voltage at pin < 0.5 VOpen:Pin openHigh:Voltage at pin > 1.5 V
Functional Description
2.4.3 Power Amplifier
The VCO frequency is divided by 2 and fed to the Power Amplifier.
The Power Amplifier can be switched on and off
by the signal at ASKDTA (pin 6).
The Power Amplifier has an Open Collector output at PAOUT (pin 9) and
requires an external pull-up coil to provide bias. The coil is part of the tuning and
matching LC circuitry to get best performance with the external loop antenna.
To achieve the best power amplifier efficiency, the high frequency voltage swing
at PAOUT (pin 9) should be twice the supply voltage.
The power amplifier has its own ground pin PAGND (pin 8) in order to reduce
the amount of coupling to the other circuits.
2.4.4 Power Modes
The IC provides three power modes, the POWER DOWN MODE, the PLL
ENABLE MODE and the TRANSMIT MODE.
2.4.4.1 Power Down Mode
In the POWER DOWN MODE the complete chip is switched off.
The current consumption is typically 0.3 nA at 3 V 25°C.
This current doubles every 8°C. The values for higher temperatures are
typically 14 nA at 85°C and typically 600 nA at 125°C.
2.4.4.2 PLL Enable Mode
In the PLL ENABLE MODE the PLL is switched on but the power amplifier is
turned off to avoid undesired power radiation during the time the PLL needs to
settle. The turn on time of the PLL is determined mainly by the turn on time of
the crystal oscillator and is less than 1 msec when the specified crystal is used.
The current consumption is typically 3.5 mA. Low:Voltage at pin < 0.5 VOpen:Pin openHigh:Voltage at pin > 1.5 V
Functional Description
2.4.4.3 Transmit Mode
In the TRANSMIT MODE the PLL is switched on and the power amplifier is
turned on too.
The current consumption of the IC is typically 7 mA when using a proper trans-
forming network at PAOUT, see Figure 3-1.
2.4.4.4 Power mode control
The bias circuitry is powered up via a voltage V > 1.5 V at the pin PDWN (pin10).
When the bias circuitry is powered up, the pins ASKDTA and FSKDTA are
pulled up internally.
Forcing the voltage at the pins low overrides the internally set state.
Alternatively, if the voltage at ASKDTA or FSKDTA is forced high externally, the
PDWN pin is pulled up internally via a current source. In this case, it is not nec-
essary to connect the PDWN pin, it is recommended to leave it open.
Functional Description
The principle schematic of the power mode control circuitry is shown in
Figure 2-5.

Other combinations of the control pins PDWN, FSKDTA and ASKDTA are not
recommended. Low:Voltage at pin < 0.7 V (PDWN)
