Functional Blocks
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 868 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 13.56 MHz.
The crystal frequency is divided by 16. The resulting 847.5 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).
