Introduction
Ceramic resonators (CERALOCK®) 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
primarily 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 applications will use
CERALOCK® because of its high stability non-
adjustment performance, miniature size and cost
savings. Typical applications include 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.
CERALOCK® is the brand name of these MURATA
products.

1. General Characteristics of CERALOCK®
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, Crystal Unit is well-known. RC
oscillation circuits and LC oscillation circuits are also used
to produce electrical resonance. The following are the
characteristics of CERALOCK®.
High stability of oscillation frequency:
Oscillation frequency stability is between that of Crystal
Units and LC or RC oscillation circuits.
The temperature coefficient of Crystal Units is 10–6/ °C
maximum and approximately 10–3 to 10–4/°C for LC or
RC oscillation circuits. For comparison these, it is 10–5/°C
at –20 to +80°C for ceramic resonators.
Small configuration and light weight:
The ceramic resonator is half the size of popular Crystal
Units.
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
affected 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.

1. Equivalent Circuit Constants
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 8), 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 8)
Fr=1/2π L

Considering the limited frequency range of FrFFa, the
impedance is given as Z=Re+jωLe (Le0) as shown in Fig.
2-4, and CERALOCK® should work as an inductance Le (H)
having the loss Re (Ω).

The table on this page shows a comparison of the equivalent
constants between CERALOCK® and
Crystal Units.
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 an
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.

(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 , the resonance frequency is Fr, the
speed of sound waves travelling through piezoelectric
ceramics, and the wavelength is
λ.
 Fr・ℓ = Const.
 (frequency constant, Frt for the thickness)
 λ = 2
 C = Fr・λ = 2Fr・ℓ
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 two terminals is expressed
by the following formula.

2. Basic Oscillation Circuits
Generally, basic oscillation circuits can be grouped into the
following 3 categories.
Use of positive feedback
Use of negative resistance element
Use of delay in transfer time or phase
In the case of ceramic resonators, Crystal Units, 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, L2 and C in
the Hartley circuit. These frequencies can be represented by
the following formulas. (Refer to Note 3 on page 11.)
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 anti-resonant
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.

In Colpitts circuit, an inverter of

inverted more than θ

circuit. The operation with a ceramic resonator can be
considered the same.

It is common and simple to utilize an inverter for the Colpitts
circuit with CERALOCK®.
Fig. 2-8 shows the basic oscillation circuit with inverter.
In an open loop circuit by cutting at point , it is possible to
measure loop gain G and phase shift
θ.

Fig. 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 ß stands
for current amplification rate.
When the oscillation circuit in Fig.2-6 is expressed by
using the equivalent circuit in Fig., it becomes like Fig.
. 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..
 β R0i1+(R0+Z2) i2–Z2i3=0………………………… (1)
 Z1i1+Z2i2–(Z2+Z+Z1) i3=0 ……………………… (2)
 (Z1+Ri) i1–Z1i3=0 ………………………………… (3)
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.
 βR0Z1Z2=(Z1+Ri)Z2
2–{Z1(Z2+Z)+
(Z2+Z+Z1)Ri}(Z2+R0) ………………… (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.
 (Imaginary number part)
  Z1Z2Z+(Z1+Z2+Z)RiR0=0 …………………… (5)
 (Real number part)
 βR0Z1Z2+Z1(Z+Z2)R0+
  Z2(Z+Z1)Ri=0 …………………………………… (6)
Formula (5) represents the phase condition and formula (6)
represents the power condition.
Oscillation frequency can be obtained by applying the
elements shown in the aforementioned table to Z1, Z2 and
Z solving it for angular frequency ω.
………………… (7)
………………… (8)
In either circuit, the term in brackets will be 1 as long as
Ri and R0 is large enough. Therefore oscillation frequency
can be obtained by the following formula.

1. Electrical Specifications
The frequency stability of CERALOCK® is between that of
Crystal Units 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 Circuits.)
Electrical Specifications of MHz Band Lead
CERALOCK® (CSTLS Series)
Electrical specifications of CSTLS series are shown in the
tables. Please note that oscillation frequency measuring
circuit constants of the CSTLS G56 series (with H-CMOS
IC) depends on frequency.
MHz band three-terminal CERALOCK® (CSTLS Series) is
built-in load capacitance.
Fig. 3-1 shows the electrical equivalent circuit.
The table shows the general specifications of the CSTLS
series. Input and output terminals of the three-terminal
CERALOCK® are shown in the table titled Dimensions of
CERALOCK® CSTLS series in Chapter 1 on page 6.
But connecting reverse, the oscillating characteristics are
not affected except that the frequency has a slight lag.

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
Crystal Units, 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
It is becoming more common to configure the oscillation
circuit with a digital IC, and the simplest way is 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 1M
Ω 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.

This clearly shows that the oscillation frequency is
influenced by the loading capacitance. Further 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 three-stage
buffer type has excessive gain, which causes RC oscillation
and ringing.
Murata employs the TOSHIBA TC4069UBP 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 H-CMOS Inverter
Recently, high-speed C-MOS (H-CMOS) have been used
more frequently for oscillation circuits allowing high speed
and energy saving control for the microprocessor.
There are two types of H-CMOS inverters: the un- buffered
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 for H-CMOS specifications is
adjusted by the circuit in Fig. 4-3.

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 it 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)
(Page18).
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.

Fig. 5-2 shows examples of actual measurements of the
oscillation level versus temperature, supply voltage and

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.

3. Characteristics of Oscillation Rise Time
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 CERALOCK® is one or
two decades faster than a Crystal Unit.
Fig. 5-5 shows comparison of rise time between the two.

CERALOCK®, by making good use of the above-mentioned
features, is used in a wide range of applications to various
kinds of ICs.
The following 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,
16-bit and 32-bit.
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 IC manufacturers about the circuit constants,
because these constants vary with frequency and the IC
circuit being used.
Murata is checking an osicllation circuit condition with
various microcomputers and CERALOCK®. The table shows
Murata recommendation circuit condition with a part of ICs
which Murata tested.
Another recomended circuit condition of many ICs has been
