General Description
The TH72036 FSK/ASK transmitter IC is designed for applications in the European 868 MHz industrialscientific-medical (ISM) band, according to the EN 300 220 telecommunications standard. 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 fc is determined by the frequency of the reference crystal fref. The integrated PLL 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: fref = fc/N, where N = 32 is the PLL feedback divider ratio. A clock signal with selectable frequency is provided. It can be used to drive a microcontroller.

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 Pout can be adjusted in four steps from Pout = -11 dBm to +9.5 dBm, either by changing the value of resistor RPS or by varying the voltage VPS at pin PSEL. The open-collector output (OUT) can be 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.

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.

2.2 FSK Modulation
FSK modulation can be achieved by pulling the crystal oscillator frequency. A CMOScompatible data stream applied at the pin FSKDTA digitally modulates the XOSC via an integrated NMOS switch. Two external pulling capacitors CX1 and CX2 allow the FSK deviation f and the center frequency fc to be adjusted independently. At FSKDTA = 0, CX2 is connected in parallel to CX1 leading to the lowfrequency component of the FSK spectrum (fmin); while at FSKDTA = 1, CX2 is deactivated and the XOSC is set to its high frequency fmax. An external reference signal can be directly ACcoupled to the reference oscillator input pin ROI. Then the transmitter is used without a crystal. Now the reference signal sets the carrier frequency and may also contain the FSK (or FM) modulation. Fig. 2: Crystal pulling circuitry

2.3 Crystal Pulling
A crystal is tuned by the manufacturer to the required oscillation frequency f0 at a given load capacitance CL and within the specified calibration tolerance. The only way to pull the oscillation frequency is to vary the effective load capacitance CLeff seen by the crystal. Figure 3 shows the oscillation frequency of a crystal as a function of the effective load capacitance. This capacitance changes in accordance with the logic level of FSKDTA around the specified load capacitance. The figure illustrates the relationship between the external pulling capacitors and the frequency deviation. 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 applications, a higher load capacitance could be chosen in order to reduce the frequency drift caused by the tolerances of the chip and the external pulling capacitors.

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 A. One current source is directly applied to the PSEL pin. The other current source is used for the generation of reference voltages with a resistor ladder. These 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 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 gating this current source.

Fig. 4: Block diagram of output power control circuitry
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.

2.8 Mode Control Logic
EN 0 1 Mode TX standby TX active CKOUT active Description TX disabled TX / CKOUT enabled
The mode control logic allows two different modes of operation as listed in the following table. The mode control pin EN is pulled-down internally. This guarantees that the whole circuit is shut down if this pin is left floating.
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 0 1
2.10 Timing Diagrams
After enabling the transmitter by the EN signal, the power amplifier remains inactive for the time ton, the transmitter start-up time. The crystal oscillator starts oscillation and the PLL locks to the desired output frequency within the time duration ton. After successful PLL lock, the LOCK signal turns on the power amplifier, and then the RF carrier can be FSK or ASK modulated.

For all soldering technologies deviating from above mentioned standard conditions (regarding peak temperature, temperature gradient, temperature profile etc) additional classification and qualification tests have to be agreed upon with Melexis. The application of Wave Soldering for SMD's is allowed only after consulting Melexis regarding assurance of adhesive strength between device and board. Melexis is contributing to global environmental conservation by promoting lead free solutions. For more information on qualification of RoHS compliant products (RoHS = European directive on the Restriction Of the Use of Certain Hazardous Substances) please visit the quality page on our website: http://www.melexis.com/quality_leadfree.aspx
