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.

Characteristics and Types of CERALOCK®

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, 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®.

① 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.

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.

Fig. 2-1 Symbol of the Two Terminal CERALOCK®
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 10.), the equivalent circuit can
be expressed as shown in Fig. 2-3.

(Note 2)
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 ℓ, the resonance
frequency is Fr, the speed of sound waves travelling
through piezoelectric ceramics, and the wavelength
is λ.
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.
① Use of positive feedback
② Use of negative resistance element
③ 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.

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

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.
Loop Gain G = α・β ≧1

θ = θ 1 + θ 2 = 360°×n (n = 1, 2,…)
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.

Specifications of CERALOCK®

1. Electrical Specifications
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 Circuits”.)

Applications of Typical Oscillation Circuits
4
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
It is becoming more common to configure the oscillation
circuit with a digital IC, and the simplest way to use an

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.

Rd : Dumping Resistor
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.
Fig. 4-1 Basic Oscillation Circuit with C-MOS Inverter
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.

Application to Typical Oscillation Circuit
Oscillation frequency fosc. in this circuit is expressed
approximately by the following equation.

(4-1)
fosc.=Fr 1+
Where, Fr=Resonance frequency of CERALOCK®

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 three-
stage 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
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.

Characteristics of CERALOCK Oscillation Circuit
5
This chapter describes the general characteristics of the basic
oscillation of Fig. 4-1 (page. 19). 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.20).
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
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.

Characteristics of CERALOCK® Oscillation Circuit

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.
Supply Voltage Characteristics
1.00
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.
0.50
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.

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
VDD (+5V)
for various kinds of microcomputers : 4-bit, 8-bit and
16-bit.
With the general frequency tolerance required for the
4, 12
