It can also be used for any other system with carrier frequencies ranging from 850 MHz to 930 MHz (e.g. for applications in the US 902 to 928 MHz ISM band). The transmitter's carrier frequency f is determined by the frequency of the reference crystal f . The integrated PLL c ref synthesizer ensures that carrier frequencies, ranging from 850 MHz to 930 MHz, can be achieved. This is done by using a crystal with a reference frequency according to: f = f /N, where N = 32 is the PLL feedback divider ratio. ref c A clock signal with selectable frequency is provided. It can be used to drive a microcontroller. Page 1 of 16 REVISION 010 - JUNE 14, 2017 3901072036

TH72036 868/915MHz FSK/ASK Transmitter 1. Theory of Operation 1.1. General As depicted in Fig.1, the TH72036 transmitter consists of a fully integrated voltage-controlled oscillator (VCO), a divide-by-32 divider (div32), a phase-frequency detector (PFD) and a charge pump (CP). An internal loop filter determines the dynamic behavior of the PLL and suppresses reference spurious signals. A Colpitts crystal oscillator (XOSC) is used as the reference oscillator of a phase-locked loop (PLL) synthesizer. The VCO’s output signal feeds the power amplifier (PA). The RF signal power P can be adjusted in four steps from P = –11 dBm to +9.5 dBm, either out out by changing the value of resistor RPSor by varying the voltage V at pin PSEL. The open-collector output (OUT) can be PS used either to directly drive a loop antenna or to be matched to a 50Ohm load. Bandgap biasing ensures stable operation of the IC at a power supply range of 1.95 V to 5.5 V. 1.2.

Functional Description 2.1. Crystal Oscillator A Colpitts crystal oscillator with integrated functional capacitors is used as the reference oscillator for the PLL synthesizer. The equivalent input capacitance CRO offered by the crystal oscillator input pin ROI is about 18pF. The crystal oscillator is provided with an amplitude control loop in order to have a very stable frequency over the specified supply voltage and temperature range in combination with a short start-up time.

TH72036 868/915MHz FSK/ASK Transmitter 2.2. FSK Modulation FSK modulation can be achieved by pulling the VCC crystal oscillator frequency. A CMOS-compatible Fig. 2: Crystal pulling circuitry data stream applied at the pin FSKDTA digitally ROI modulates the XOSC via an integrated NMOS switch. Two external pulling capacitors CX1 and CX2 XTAL allow the FSK deviation f and the center frequency FSKSW f to be adjusted independently. At FSKDTA = 0, CX2 c is connected in parallel to CX1 leading to the low- CX2 frequency component of the FSK spectrum (f ); CX1 min while at FSKDTA = 1, CX2 is deactivated and the VEE XOSC is set to its high frequency f . max An external reference signal can be directly AC- coupled to the reference oscillator input pin ROI. Then the transmitter is used without a crystal. Now FSKDTA Description the reference signal sets the carrier frequency and may also contain the FSK (or FM) modulation. 0 f = f - f (FSK switch is closed) min c 1 f = f + f (FSK switch is open) max c 2.3. Crystal Pulling A crystal is tuned by the manufacturer to the f required oscillation frequency f at a given load 0 capacitance CL and within the specified calibration tolerance. The only way to pull the oscillation XTAL frequency is to vary the effective load capacitance CLeff seen by the crystal. L1 Figure 3 shows the oscillation frequency of a crystal fmax as a function of the effective load capacitance. This C1 C0 CLeff capacitance changes in accordance with the logic R1 level of FSKDTA around the specified load fc capacitance. The figure illustrates the relationship between the external pulling capacitors and the frequency deviation. fmin It can also be seen that the pulling sensitivity increases with the reduction of CL. Therefore, applications with a high frequency deviation require a low load capacitance. For narrow band FSK CLeff applications, a higher load capacitance could be CX1 CRO CL (CX1+CX2) CRO CX1+CRO CX1+CX2+CRO chosen in order to reduce the frequency drift caused by the tolerances of the chip and the external pulling capacitors. Fig. 3: Crystal pulling characteristic For ASK applications CX2 can be omitted. Then CX1 has to be adjusted for center frequency. Page 5 of 16 REVISION 010 - JUNE 14, 2017 3901072036

TH72036 868/915MHz FSK/ASK Transmitter 2.4. ASK Modulation The TH72036 can be ASK-modulated by applying data directly at pin PSEL. This turns the PA on and off which leads to an ASK signal at the output. 2.5. Output Power Selection The transmitter is provided with an output power selection feature. There are four predefined output power steps and one off-step accessible via the power selection pin PSEL. A digital power step adjustment was chosen because of its high accuracy and stability. The number of steps and the step sizes as well as the corresponding power levels are selected to cover a wide spectrum of different applications. The implementation of the output power control logic is shown in figure 4. There are two matched current sources with an amount of about 8 µA. One current source is directly applied to the PSEL pin. RPS The other current source is used for the generation of reference voltages with a resistor ladder. These PSEL reference voltages are defining the thresholds between the power steps. The four comparators & deliver thermometer-coded control signals depending on the voltage level at the pin PSEL. In & & & & order to have a certain amount of ripple tolerance in a noisy environment the comparators are provided with a little hysteresis of about 20 mV. With these control signals, weighted current sources of the power amplifier are switched on or OUT off to set the desired output power level (Digitally Controlled Current Source). The LOCK, ASK signal and the output of the low voltage detector are Fig. 4: Block diagram of output power control circuitry gating this current source. There are two ways to select the desired output power step. First by applying a DC voltage at the pin PSEL, then this voltage directly selects the desired output power step. This kind of power selection can be used if the transmission power must be changed during operation. For a fixed-power application a resistor can be used which is connected from the PSEL pin to ground. The voltage drop across this resistor selects the desired output power level. For fixed- power applications at the highest power step this resistor can be omitted. The pin PSEL is in a high impedance state during the “TX standby” mode. 2.6. Lock Detection The lock detection circuitry turns on the power amplifier only after PLL lock. This prevents from unwanted emission of the transmitter if the PLL is unlocked. 2.7. Low Voltage Detection The supply voltage is sensed by a low voltage detect circuitry. The power amplifier is turned off if the supply voltage drops below a value of about 1.85 V. This is done in order to prevent unwanted emission of the transmitter if the supply voltage is too low. Page 6 of 16 REVISION 010 - JUNE 14, 2017 3901072036

TH72036 868/915MHz FSK/ASK Transmitter 2.8. Mode Control Logic The mode control logic allows two different modes EN Mode Description of operation as listed in the following table. The 0 TX standby TX disabled mode control pin EN is pulled-down internally. This guarantees that the whole circuit is shut down if 1 TX active TX / CKOUT this pin is left floating. CKOUT active enabled 2.9. Clock Output The clock output CKOUT is CMOS-compatible and can be used to drive a microcontroller. The frequency of the clock can be selected by the clock divider control signal CKDIV, according to the following table. A capacitor at pin CKOUT can be used to control the clock voltage swing and the RF spurious emission. CKDIV Clock divider ratio Clock frequency / f=868.3MHz c 0 8 3.39MHz 1 32 848kHz 2.10. Timing Diagrams After enabling the transmitter by the EN signal, the power amplifier remains inactive for the time t , the transmitter on start-up time. The crystal oscillator starts oscillation and the PLL locks to the desired output frequency within the time duration t . After successful PLL lock, the LOCK signal turns on the power amplifier, and then the RF carrier can be FSK on or ASK modulated. high high EN EN low low high high LOCK LOCK low low high high FSKDTA PSEL low low RF carrier t t t t on on Fig. 5: Timing diagrams for FSK and ASK modulation Page 7 of 16 REVISION 010 - JUNE 14, 2017 3901072036
