The different modes of operation are controlled by the microcontroller through several digital input pins. The power supply voltage ranges from 1.9V to 3.6V allowing operation with a single lithium cell. PHASE LOCKED LOOP AND LOCAL OSCILLATOR The VCO is a completely integrated relaxation oscillator. The Phase Frequency Detector (PFD) and the loop filter are fully integrated.The exact output frequency is equal to: fRFOUT = fXTAL x PLL divider ratio. The frequency band of operation is selected through the BAND pin. Table 1 provides details for each frequency band selection. Table 1: Frequency band selection and associated divider ratios BAND input Frequency PLL divider Crystal oscillator level band (MHz) ratio frequency (MHz) 315 9.84 High 32 434 13.56 Low 868 64 An out-of-lock function is performed by monitoring the PFD output voltage. When it exceeds defined limits, the RF output stage is disabled. RF OUTPUT STAGE The output stage is a single ended square wave switched current source. Harmonics are present in the output current drive. Their radiated absolute level depends on the antenna characteristics and output power. Typical application demonstrates compliance to ETSI standard. A resistor Rext connected to the REXT pin controls the output power allowing a trade-off between radiated power and current consumption. The output voltage is internally clamped to Vcc 2Vbe (typ. Vcc 1.5V @ TA=25C). MODULATION A low logic level has to be applied on pin MODE to select the On Off Keying (OOK) modulation. This modulation is performed by switching on/off the RF output stage. The logic level applied on pin DATA controls the output stage state: DATA=0 -> output stage off, DATA=1 -> output stage on. If a high logic level is applied on pin MODE, then Frequency Shift Keying (FSK) modulation is selected. This modulation is achieved by crystal pulling. An internal switch connected to CFSK pin enables to switch the external crystal load capacitors. Figure 2 shows the possible configurations: serial and parallel. The logic level applied on pin DATA controls the state of this internal switch: DATA=0 -> switch off, DATA=1 -> switch on. DATA input is internally re-synchronized by the crystal reference signal. The corresponding jitter on the data duty cycle cannot exceed 1 reference period (75ns for a 13.56MHz crystal). This crystal pulling solution implies that the RF output frequency deviation equals the crystal frequency deviation multiplied by the PLL divider ratio (see table 1). MOTOROLA SEMICONDUCTORS PRODUCTS 3 MC33493 Figure 2: Crystal pulling configurations MICROCONTROLLER INTERFACE Four digital input pins (ENABLE, DATA, BAND and MODE) enable the circuit to be controlled by a microcontroller. It is recommended to configure the band frequency and the modulation type before enabling the circuit. One digital output (DATACLK) provides to the microcontroller a reference frequency for data clocking.This frequency is equal to the crystal oscillator frequency divided by 64 (see table 2). Table 2: DATACLK frequency versus crystal oscillator frequency Crystal oscillator DATACLK frequency (MHz) frequency (kHz) 9.84 154 13.56 212 MOTOROLA SEMICONDUCTORS PRODUCTS 4 MC33493 STATE MACHINE Figure 3 details the state machine. Figure 3: State machine Power ON AND ENABLE=0 State 1 Standby mode ENABLE=0 ENABLE=1 State 2 PLL out of lock-in range No RF output PLL in lock-in range PLL out of lock-in range ENABLE=0 State 4 Shutdown mode VBattery < VShutdown State 3 Transmission mode State 1: The circuit is in standby mode and draws only a leakage current from the power supply. State 2: In this state, the PLL is out of the lock-in range. Therefore the RF output stage is switched off preventing RF transmission. Data clock is available on pin DATACLK. Each time the device is enabled, the state machine passes through this state. State 3: In this state, the PLL is within the lock-in range. If t<tPLL_lock_in then the PLL can still be in acquisition mode. If ttPLL_lock_in, then the PLL is locked. Data entered on pin DATA are output on pin RFOUT according to the modulation selected by the level applied on pin MODE. State 4: When the supply voltage falls below the shutdown voltage threshold (VSDWN) the whole circuit is switched off. Applying a low level on pin ENABLE is the only condition to get out of this state. MOTOROLA SEMICONDUCTORS PRODUCTS 5 MC33493 Figure 4 shows the waveforms of the main signals for a typical application cycle. Figure 4: Signals waveforms and timings definition ENABLE DATACLK tDATACLK_settling tPLL_lock_in DATA MODE=0 (OOK) RFOUT MODE=1 (FSK) fcarrier fhigh State 1 flow State 2 fcarrier fhigh State 3 flow fhigh State 1 : PLL locked POWER MANAGEMENT When the battery voltage falls below the shutdown voltage threshold (VSDWN) the whole circuit is switched off. It has to be noted that after this shutdown, the circuit is latched until a low level is applied on pin ENABLE (see state 4 of the state machine). DATA CLOCK At start-up data clock timing is valid after the data clock settling time. As clock is switched off asynchronously, the last period duration cannot be guaranteed.

Three different spans have been used. The 5MHz span spectrum (figure 5) shows phase noise response close to the RF carrier, and the noise suppression within the PLL loop bandwidth. The 50MHz span spectrum (figure 6) shows both phase noise and reference spurious. Finally figure 7 shows second and third harmonics of carrier. All these spectrums are measured in OOK modulation, at DATA=1. Figure 8 shows spectrum in case of FSK modulation, with 45kHz deviation, at 4kbit/s data rate.

This load capacitance is constituted by various contributors: - the crystal characteristic, especially its static capacitance, - the external load capacitors (C3, C4 as defined in figure 14 and table 6), - the device internal capacitance of pins XTAL0, XTAL1, CFSK, - the PCB track capacitance. The schematic given in figure 16 shows a typical FSK application using serial capacitor configuration, where device pads and PCB track capacitances are mentioned. Device pad capacitance is defined by the package capacitance and by the internal circuitry. Typical capacitance values for these pads are given in table 8. Some realistic assumptions and measurements have been made concerning track parasitic capacitances for a 0.8mm FR4 double side application PCB. They are given in table 8, and the corresponding PCB layout in figure 15. To achieve large deviations, this total load capacitance need to be lowered. For a given crystal, the PCB must very carefully laid out in order to reduce as much as possible the capacitance of the tracks wired to XTAL0, XTAL1, CFSK pins. Recommendation: a R_off resistor can be added in parallel with the FSK switch to optimize the transient response of demodulated signal. Table 6 gives the optimized R_off values for two deviations. Note that there is no footprint for R_off resistor on the layout figure 15. When used, this component can be soldered on top of C3.
