General Description
The TH72016 FSK/ASK transmitter IC is designed for applications in the European 433 MHz industrialscientific-medical (ISM) band, according to the EN 300 220 telecommunications standard; but it can also be
used in other countries with similar standards, e.g. FCC part 15.231.
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 380 MHz to 450 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.

FSK/ASK Transmitter
1 Theory of Operation
1.1 General
As depicted in Fig.1, the TH72016 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 = –12 dBm to +10 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 Δf 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.

fmax= fc + Δf (FSK switch is open)
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 TH72016 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. 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 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.

Mode Control Logic
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

emission.

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.

7 Reliability Information
This Melexis device is classified and qualified regarding soldering technology, solderability and moisture
sensitivity level, as defined in this specification, according to following test methods:
Reflow Soldering SMD’s (Surface Mount Devices)
•
IPC/JEDEC J-STD-020
“Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices (classification reflow profiles according to table 5-2)”
Wave Soldering SMD’s (Surface Mount Devices)
•
EN60749-20
“Resistance of plastic- encapsulated SMD’s to combined effect of moisture and soldering heat”
Solderability SMD’s (Surface Mount Devices)
•
EIA/JEDEC JESD22-B102
“Solderability”
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.
8 ESD Precautions
Electronic semiconductor products are sensitive to Electro Static Discharge (ESD).
Always observe Electro Static Discharge control procedures whenever handling semiconductor products.
