FSK demodulation with PSoC CY8C27443

Ngo Dien Tap and Nguyen Kiem Hung 
College of Technology, VNU Hanoi 
Abstract'. Frequency Shift Key (FSK) is the

most common form of digital modulation in the 
high-frequency radio spectrum, and has a lot of 
important applications in low-speed data 
communications. Recently, FSK modulator and 
demodulator can be implemented easily thank 
to appearance of high performance 8-bit, 
embedded micro-controllers. This paper 
introduces the use of available on-chip 
resources on a PsoC micro-controller to 
perform FSK demodulation. A FSK generator 
also was built on CY8C27443 micro-controller 
in order to support testing function of the 
demodulator.

I. INTRODUCTION

Many measurement applications (for
example, electric and gas meters) require a
way to communicate electronically with a
central office so that measured data can be
reported back to the central office and new
tariffs can be set in the remote site. Frequency
shift keying (FSK) are one popular methods
of representing binary data over copper
cables.

With FSK, the transmitter converts a bit
stream ( T s or O's) into a varying frequency
that can be easily transmitted over
communication lines. At the receiving end,

the receiver gets this modulated signal and
transform it back into a bit stream. Obviously,
FSK is a simple, inexpensive, easy way to
achieve low-speed communications. This
application describes implementation of a
FSK demodulator by a PSoC
micro-controller. The demodulator is tested by a

FSK modulated signal that uses 1500 Hz to
represent a ' T and 2000 Hz to represent a '0'.
The maximum data rate for this type of
modulation is 1200 baud. Integrating the
measurement and communication functions
onto the same chip yields cost as well as
power-saving benefits.

Modulation Theory

FSK modulation involves alternating the
value of frequency deviation from a carrier
frequency according to the value of the bit to
be represented. For this application, a bit
value of 0 = 500 Hz and a bit value of 1 =
-500 Hz.

FSK signal = A*cos[t*2*7r*(Fc ± F^)]
where, F^ = 2000 Hz is carrier frequency. V^

= +/- 500 Hz frequency deviation from a

carrier frequency according to the value of the
bit to be represented.

Demodulation Theory

A quadrature demodulator is able to used

to provide the FSK demodulation. In this type
of demodulation, the signal and its delayed
version are multiplied together and then
low-pass filtered. If the delay, T. is set such that

o}^* T = 7t/2, then the low-pass filter result is

proportional to the frequency deviation from
the carrier and therefore represents the bit
value sent.

</div>
(54)<div class='page_container' data-page=54>

If 03 = 03^ + 0)^ and T * 03^ = 7c/2,

(Where, co= 27rf, 03^ earner frequency, ±co^
frequency deviation from a carrier frequency
according to the value of the bit to be
represented.)

then:

2*cos[cot]*cos[o3(t-T)] = coscoT + cos(2(j3t-coT)

After low-pass filtered, result in:
cos(03T) = sin[±03jj] = ±sin[a3d]

Another way to demodulate FSK is
method of frequency measurement. Recall
that, FSK modulation involves the use of two
frequencies. One frequency is used to
represent a digital 1, while another frequency
is used to represent a digital 0. FSK can be
mathematically remodeled by equation:

f A*cos(t*2*7i:*Fi), ifd(t)=l
FSK signal = i

lA*cos(t*2*7r*F2), ifd(t)-0
where, d(t) is the incoming data bit stream.

Figure I: Digital data and corresponding FSK

signal.

Thereby, if we have a micro-controller that
fast enough to capture frequencies used in
FSK modulation then we are able to FSK
demodulation.

The latter is simple and suitable to

application of CY8C27443 micro-controller.
II. EXPERIMENT

Implementation of FSK Demodulation

It is possible to implement an FSK
demodulator using only the PSoC device. The
following PSoC Designer User Modules are
required in order to build the application:

• Two Programmable Gain Amplifier
(PGA) blocks.

• One comparator.
• One 8-bit timer.
• One 16-bit timer.

The following figure 2 shows block diagram
of implementation of a FSK demodulator.

Figure 2: Block diagram of FSK receiver.

Firstly, the FSK signal is passed through a
amplifier which consists of two PDA blocks
of PSoC. This amplifier is used to clip input
signal, to output a signal approximate square
wave. The combined gain is selected so that
the signal is correctly clipped. The resulting
signal is then sent to a comparator. The
comparator is set to trigger at 0 V. Thereby,
the comparator acts as a zero crossing
detector on the incoming signal.

The square signal from the comparator is
routed to the counter. An 8-bit timer, clocked
by the 32 KHz clock, helps in this task. The

value of the timer is captured every time the
comparator triggers. By comparing 2
consecutive values of the timer, the value of
the incoming frequency can be determined.
The FSK center frequency, 2 KHz,
corresponds to 16 cycles (32/2) of the 32 KHz
clock.

The software implementation of FSK is
very simple (see figure 3). The software times
the transitions on the input signal. The value
of the timer is read every time the transition
occurs. If the transitions happen within a
specified time, then a high frequency is being
detected, otherwise a low' frequency is being
detected. The program sets the output pin of
the counter high or low depending on the
frequency detected.

Bit Synchronization

The bit values coming out from
demodulation need to be determined and
synchronized to produce the incoming data bit
stream. This process is also known as bit
slicing and clock recover}. This is done
through a bit count-down counter. The

</div>
(55)<div class='page_container' data-page=55>

bit timer generates an interrupt every 1/1200
s. This interrupt is used to recover the bit rate

from the incoming FSK signal (see figure 4).

At this point, the PSoC-implemented FSK

demodulator has been built. The layout of all
elements on the board is shown on the Figure
6. To be convenient for testing, we have
included a LED display panel into the FSK
receiver. Digital data, for example
temperature is measured and then modulated
and transfered to the receiver via a
communication line is demodulated and
displayed on the LED panel. Now it is time to
test the project and confirm proper
fiinctionality. With the use of oscilloscope
(Agilent 54642A, in our experiment), the
following figure 7 illustrates FSK signal and
corresponding digital data of the demodulator.

III. CONCLUSION.

Thank to the available on-chip resources of
PSoC, it is easy to build FSK modulation and
demodulation. Recently, many measurement
systems based on PSoC was implemented,
hence, this modulator and demodulator can be

INTEGRATE SPECIFIC CHIPS INTO THE PHYSICAL
MEASURING SYSTEMS

Abstract: All modem physical measuring systems include two major parts: sensors

and signal processing block. Recent great achievements in Physics have produced
advanced sensors, and at the same time the advancements of technology so lead to
the incessantly development of measuring processors.

The technology of PSoc (Programmable System on Chip) and CPLD (Complex
Programmable Logic Device) with the common feature of embedding software mto
hardware of device, allow us to develop dedicated chips with expected features.
