Introduction
CERALOCK® is the trade mark of Murata's ceramic
resonators. These components are made of high stability
piezoelectric ceramics that function as a mechanical
resonator.
This device has been developed to function as a
reference signal generator and the frequency is primary
adjusted by the size and thickness of the ceramic
element.
With the advance of the IC technology, various
equipment may be controlled by a single LSI integrated
circuit, such as the one-chip microprocessor.
CERALOCK® can be used as the timing element in most
microprocessor based equipment.
In the future, more and more application will use
CERALOCK® because of its high stability nonadjustment performance, miniature size and cost
savings. Typical application includes TVs, VCRs,
automotive electronic devices, telephones, copiers,
cameras, voice synthesizers, communication equipment,
remote controls and toys.
This manual describes CERALOCK® and will assist you
in applying it effectively.

1 Characteristics and Types of CERALOCK®
1. General Characteristics of CERALOCK®
1
Ceramic resonators use the mechanical resonance of
piezoelectric ceramics. (Generally, lead zirconium
titanate : PZT.)
The oscillation mode varies with resonant frequency.
The table on the right shows this relationship.
As a resonator device, quartz crystal is well-known. RC
oscillation circuits and LC oscillation circuits are also
used to produce electrical resonance. The following are
the characteristics of CERALOCK®.
q High stability of oscillation frequency
Oscillation frequency stability is between that of the
quartz crystal and LC or RC oscillation circuits. The
temperature coefficient of quartz crystal is 10–6/°C
maximum and approximately 10–3 to 10–4/°C for LC or
RC oscillation circuits. Compared with these, it is
10–5/°C at –20 to +80°C for ceramic resonators.
w Small configuration and light weight
The ceramic resonator is half the size of popular quartz
crystals.
e Low price, non-adjustment
CERALOCK® is mass produced, resulting in low cost
and high stability.
Unlike RC or LC circuits, ceramic resonators use
mechanical resonance. This means it is not basically
effected by external circuits or by the fluctuation of the
supply voltage.
Highly stable oscillation circuits can therefore be made
without the need of adjustment.
The table briefly describes the characteristics of various
oscillator elements.

2. Types of CERALOCK®
kHz Band CERALOCK® (CSB Series)
The CSB series uses are a vibration mode of the
piezoelectric ceramic element. The dimensions of this
element vary with frequency. The ceramic element is
sealed in a plastic case and the size of the case also
varies with the frequency band. Washable products are
available in all the frequencies ; However, three
standard products (375 to 699kHz) are also made in less
expensive non-washable models.

Considering the limited frequency range of FrVFVFa,
the impedance is given as Z=Re+jωLe (LeU0) as shown
in Fig.2-4, and CERALOCK® should work as an
inductance Le (H) having the loss Re (Ω).

Fig.2-1 shows the symbol for a ceramic resonator. The
impedance and phase characteristics measured between
the terminals are shown in Fig.2-2. This illustrates that
the resonator becomes inductive in the frequency zone
between the frequency Fr (resonant frequency), which
provides the minimum impedance, and the frequency Fa
(anti-resonant frequency), which provides the maximum
impedance.
It becomes capacitive in other frequency zones. This
means that the mechanical vibration of a two-terminal
resonator can be replaced equivalently with a
combination of series and parallel resonant circuits
consisting of an inductor : L, a capacitor : C, and a
resistor : R. In the vicinity of the specific frequency
(Refer to Note 1 on page 12.), the equivalent circuit can
be expressed as shown in Fig.2-3.
Fr and Fa frequencies are determined by the
piezoelectric ceramic material and the physical
parameters. The equivalent circuit constants can be
determined from the following formulas. (Refer to Note
2 on page 12.)

The table on this page shows comparison for the
equivalent constants between CERALOCK® and quartz
crystal oscillator.
In comparison, there is a large difference in capacitance
and Qm, which results in the difference of oscillating
conditions, when actually operated.
The table in the appendix shows the standard values of
equivalent circuit constant for each type of
CERALOCK®. Furthermore, other higher harmonic
modes exist, other than the desired oscillation mode.
These other oscillation modes exist because the ceramic
resonator uses mechanical resonance.
Fig.2-5 shows those characteristics.

Notes
(Note 1)
The relationship between the size of the resonator
and the resonant frequency is described as follows.
For example, the frequency doubles if the thickness
doubles, when thickness vibration is used.
The following relationship is obtained when the
length of the resonators is r, the resonance
frequency is Fr, the speed of sound waves travelling
through piezoelectric ceramics, and the wavelength
is λ.
Fr·r = Const.
(frequency constant, Fr·t for the thickness)
λ = 2r
C = Fr·λ = 2Fr·r
As seen in the above formula, the frequency
constant determines the size of the resonator.
(Note 2)
In Fig.2-3, when resistance R1 is omitted for
simplification, the impedance Z (ω) between 2
terminals is expressed by the following formula.

2. Basic Oscillation Circuits
Generally, basic oscillation circuits can be grouped into
the following 3 categories.
q Use of positive Feedback
w Use of negative resistance element
e Use of delay in transfer time or phase
In the case of ceramic resonators, quarts crystal
oscillators, and LC oscillators, positive feedback is the
circuit of choice.
Among the positive feedback oscillation circuit using an
LC, the tuning type anti-coupling oscillation circuit,
Colpitts and Hartley circuits are typically used.
See Fig.2-6.
In Fig.2-6, a transistor, which is the most basic
amplifier, is used.
The oscillation frequencies are approximately the same
as the resonance frequency of the circuit consisting of L,
CL1 and CL2 in the Colpitts circuit or consisting of L1
and L2 in the Hartley circuit. These frequencies can be
represented by the following formulas. (Refer to Note 3
on page 15.)

(2-5)
In an LC network, the inductor is replaced by a ceramic
resonator, taking advantage of the fact that the
resonator becomes inductive between resonant and antiresonant frequencies.
This is most commonly used in the Colpitts circuit.
The operating principle of these oscillation circuits can
be seen in Fig.2-7. Oscillation occurs when the following
conditions are satisfied.
Loop Gain G = α · β U1
Phase Amount
θ = θ 1 + θ 2 = 360°×n (n = 1, 2, ···)
(2-6)
In Colpitts circuit, an inverter of θ 1 = 180° is used, and
it is inverted more than θ 2 = 180° with L and C in the
feedback circuit. The operation with a ceramic resonator
can be considered the same.

Notes
(Note 3)
Fig.3 shows the equivalent circuit of an emitter
grounding type transistor circuit. In the figure, Ri
stands for input impedance , R0 stands for output
impedance and β stands for current amplification
rate.
When the oscillation circuit in Fig.2-6 is expressed
by using the equivalent circuit in Fig.3, it becomes
like Fig.4. Z1, Z2 and Z are as shown in the table
for each Hartley type and Colpitts type circuit.
The following 3 formulas are obtained based on
Fig.4.

Then, as Z1, Z2 and Z are all imaginary numbers,
the following conditional formula is obtained by
dividing the formula (4) into the real number part
and the imaginary number part.

As i1 ≠ 0, i2 ≠ 0 , i3 ≠ 0 are required for continuous
oscillation, the following conditional formula can be
performed by solving the formulas of (1), (2) and (3)
on the current.

3 Specifications of CERALOCK®
1. Electrical Specifications
3
The frequency stability of CERALOCK® is between that
of crystal and LC or RC oscillators. Temperature
stability is ±0.3 to ±0.5% against initial values within
-20 to +80°C. The initial frequency precision is
±0.5% for standard products. The frequency of the
standard CERALOCK® is adjusted by the standard
measuring circuit, but the oscillation frequency may
shift when used in the actual IC circuit. Usually, if the
frequency precision needed for clock signal of a 1 chip
microcomputer is approximately ±2 to 3% under
working conditions, CERALOCK® standard type can be
used in most cases. If exact oscillation frequency is
required for a special purpose, Murata can manufacture
the ceramic resonator for the desired frequency.
The following are the general electrical specifications of
CERALOCK®. (As for the standard measuring circuit of
oscillation frequency, please refer to the next chapter
“Application to Typical Oscillation Circuit”.)

4 Application to Typical Oscillation Circuit
As described in Chapter 2, the most common oscillation
circuit with CERALOCK® is to replace L of a Colpitts
circuit with CERALOCK®. The design of the circuit
varies with the application and the IC being used, etc.
Although the basic configuration of the circuit is the
same as that of a quartz crystal, the difference in
mechanical Q results in the difference of the circuit
constant.
This chapter briefly describes the characteristics of the
oscillation circuit and gives some typical examples.
1. Cautions for Designing Oscillation Circuits
4
It is becoming more common to configure the oscillation
circuit with a digital IC, and simplest way to use an
inverter gate.
Fig.4-1 shows the configuration of a basic oscillation
circuit with a C-MOS inverter.
INV. 1 works as an inverter amplifier of the oscillation
circuit. INV. 2 acts to shape the waveform and also acts
as a buffer for the connection of a frequency counter.
The feedback resistance Rf provides negative feedback
around the inverter in order to put it in the linear
region, so the oscillation will start, when power is
applied.
If the value of Rf is too large, and if the insulation
resistance of the input inverter is accidentally
decreased, oscillation will stop due to the loss of loop
gain. Also, if Rf is too great, noise from other circuits
can be introduced into the oscillation circuit.
Obviously, if Rf is too small, loop gain will be low. An Rf
of 1MΩ is generally used with a ceramic resonator.
Damping resistor Rd provides loose coupling between
the inverter and the feedback circuit and decreases the
loading on the inverter, thus saving energy.
In addition, the damping resistor stabilizes the phase of
the feedback circuit and provides a means of reducing
the gain in the high frequency area, thus preventing the
possibility of spurious oscillation.
Load capacitance CL1 and CL2 provide the phase lag of
180°.
The proper selected value depends on the application,
the IC used, and the frequency. If CL1 and CL2 values
are too low, the loop gain in the high frequency is
increased, which in turn increases the probability of
spurious oscillation.
This is particularly likely around 4 to 5 MHz, where the
thickness vibration mode lies, as shown in Fig.2-5 when
using kHz band resonator.

Where,

This clearly shows that the oscillation frequency is
influenced by the loading capacitance. And caution
should be paid in defining its value when a tight
tolerance of oscillation frequency is required.

2. Application to Various Oscillation Circuits
Application to C-MOS Inverter
For the C-MOS inverting amplifier, the one-stage 4069
C-MOS group is best suited.
The C-MOS 4049 type is not used, because the threestage buffer type has excessive gain, which causes RC
oscillation and ringing.
Murata employs the RCA(HARRIS) CD4069UBE as a
C-MOS standard circuit. This circuit is shown in
Fig.4-2. The oscillation frequency of the standard
CERALOCK® (C-MOS specifications) is adjusted by the
circuit in Fig.4-2.

Application to Typical Oscillation Circuit
Application to H-MOS Inverter
4
Recently, high speed C-MOS (H-CMOS) have been used
more frequently for oscillation circuit allowing high
speed and energy saving control for the microprocessor.
There are two types of H-CMOS inverters : the unbuffered 74HCU series and the 74HC series with
buffers.
The 74HCU system is optimum for the CERALOCK®
oscillation circuit.
Fig.4-3 shows our standard H-CMOS circuit.
Since H-CMOS has high gain, especially in the high
frequency area, greater loading capacitor (CL) and
damping resistor (Rd) should be employed to stabilize
oscillation performance. As a standard circuit, we
recommend Toshiba's TC74CU04, but any 74HCU04
inverter from other manufacturers may be used.
The oscillation frequency of CSA-040 series and
CSB-40 series for H-CMOS specifications is adjusted
by the circuit in Fig.4-3.

5 Characteristics of CERALOCK® Oscillation Circuit
This chapter describes the general characteristics of the basic
oscillation of Fig.4-1(P.22). Contact Murata for detailed
characteristics of oscillation with specific kinds of ICs and LSIs.
1. Stability of Oscillation Frequency
Fig.5-1 shows examples of actual measurements for stability of
the oscillation frequency.
The stability versus temperature change is ±0.1 to 0.5% within
a range of -20 to +80°C, although varies slightly depending on
the ceramic material.
Influence of load capacitance (CL1, CL2) on the oscillation
frequency is relatively high, as seen in formula (4-1) (P.23).
It varies approximately ±0.05% for a capacitance deviation of
±10%. The stability versus supply voltage is normally within
±0.05% in the working voltage range, although it varies with
the characteristics of the IC.

2. Characteristics of the Oscillation Level
The Fig.5-2 shows examples of actual measurements of
the oscillation level versus temperature, supply voltage
and load capacitance (CL1, CL2). The oscillating
amplitude is required to be stable over a wide
temperature range, and temperature characteristics
should be as flat as possible. The graph titled Supply
Voltage Characteristics in Fig.5-2 shows that the
amplitude varies linearly with supply voltage, unless
the IC has an internal power supply voltage regulator.

Rise Time (ms)

Oscillation rise time means the time when oscillation
develops from a transient area to a steady state
condition, at the time the power of the IC is activated.
With a CERALOCK®, this is defined as the time to reach
90% of the oscillation level under steady state
conditions as shown in Fig.5-3.
Rise time is primarily a function of the oscillation circuit
design. Generally, smaller loading capacitance, higher
frequency of ceramic resonator, and lower mechanical Q
of ceramic resonator cause a faster rise time. The effect
of load capacitance becomes more apparent as the
capacitance of the resonator decreases.
Fig.5-4 shows how the rise time increases as the load
capacitance of the resonator increases. Also, Fig.5-4
shows how the rise time varies with supply voltage.
It is noteworthy that the rise time of the ceramic
resistor is one or two decades faster than a quartz
crystal.
Fig.5-5 shows comparison of rise time between the two.

6 Application Circuits to Various ICs/LSIs
CERALOCK®, by making good use of the above mentioned features, is used in a
wide range of applications to various kinds of ICs.
The followings are a few examples of actual applications.
1. Application to Microcomputers
CERALOCK® is optimum for a stable oscillation element
for various kinds of microcomputers : 4-bit, 8-bit and 16bit.
With the general frequency tolerance required for the
reference clock of microcomputers at ±2 to ±3%,
standard CERALOCK® meets this requirement. Please
consult with MURATA or LSI manufacturers about the
circuit constants, because these constants vary with
frequency and the LSI circuit being used.
Fig.6-1 to 6-6 show applications to various kinds of
4-bit microcomputers, and Figs.6-7 to 6-15 show
applications to 8-bit microcomputers.

2. Application to Remote Control ICs
Remote controllers have become an increasingly more
popular feature in TVs, stereos, VCRs, and air
conditioners.
Fig.6-16 to 6-18 show examples of CERALOCK® in
remote control transmission ICs. Oscillation frequency
is normally 400 to 500kHz, with 455kHz being the most
popular. This 455kHz is divided by a carrier signal
generator, so that a carrier of approximately 38kHz is
generated.

3. Application to Various Kinds of VCOs (Voltage Controlled Oscillators)
VCO circuits are used in TVs and audio equipment, because the
signals need to be processed in synchronization with pilot signals
transmitted from broadcasting stations. Oscillation circuits, such as
LC and RC, were previously often used, but CERALOCK® is now
widely used as well, because they require no adjustment and have
superior stability over the older type circuit.
Resonators, for VCO applications, are required to have a wide
variable frequency range. We supply CERALOCK® devices with
specially designed ceramic materials for VCO applications.

4. Application to Telephone Dialers
The latest developments in telephone technology make it
a highly advanced communication terminal. With the
change from the pulse dialer to the tone dialer, the
telephone key pad can be used for an effective data
transmission. The frequency tone of each key is
determined by the combination of the allocated frequency
tone of the column and row keys. It is mandatory to
observe an overall frequency tolerance of 1.5% under any
servicing conditions. Since ICs normally have a division
error of 0.1 to 0.75%, a maximum of ±0.6% frequency
tolerance is allowed for the oscillator of the tone dialer.

Application Circuits to Various ICs/LSIs
In order to satisfy this frequency accuracy, we developed
the 3.58MHz CERALOCK® “CSTS0358MG3 series” which
is tuned for each IC.
Due to the outstanding features of CERALOCK® such as
lower cost, lighter weight, and faster rise-up time, it is
widely replacing the quartz crystal.
Fig.6-24 to Fig.6-26 are some examples for various dialer
ICs. For more information, “Piezoelectric Components
