General Description
The TH72036 FSK/ASK transmitter IC is designed for applications in the European 868 MHz industrial-scientific-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.

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.
1.2. Block Diagram

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 CMOS-compatible
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 low-
frequency 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 AC-
coupled 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.

fmin= fc - f (FSK switch is closed)

fmax= fc + f (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.

For ASK applications CX2 can be omitted. Then CX1 has to be adjusted for center frequency.

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.
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
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.

2.10. 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.
