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®.

①High 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. For comparison

these, it is 10–5/°C at –20 to +80°C for ceramic

resonators.

② Small configuration and light weight:

The ceramic resonator is half the size of popular

quartz crystals.

③ 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.

Impedance between Two Terminals Z=R+jx

(R : Real Component, X : Impedance Component)

Phase φ =tan-1X/R

Fig. 2-1 Symbol for the Two-Terminal CERALOCK®

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)

Considering the limited frequency range of Fr≦F≦Fa,

the impedance is given as Z=Re+j

ω

Le (Le≧0) as shown

in Fig. 2-4, and CERALOCK® should work as an

inductance Le (H) having the loss Re (Ω).

Principles of CERALOCK®

The table on this page shows a comparison of the

equivalent constants between CERALOCK® and a

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

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 ℓ, the resonance

frequency is Fr, the speed of sound waves travelling

through piezoelectric ceramics, and the wavelength

is λ.

Fr.ℓ = Const.

(frequency constant, Fr.t for the thickness)

λ = 2 ℓ

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.

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, quartz 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 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.

It is common and simple to utilize an inverter for the

Colpitts circuit with CERALOCK®.

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.

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.

3Specifications 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”.)

1. Cautions for Designing Oscillation Circuits

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.

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 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.

2. Application to Various Oscillation Circuits

Oscillation frequency fosc. in this circuit is expressed

approximately by the following equation.

Where, Fr=Resonance frequency of CERALOCK®

Where, C1 : Equivalent series capacitance of

Where, C1 : CERALOCK®

Where, C0 : Equivalent parallel capacitance of

Where, C1 : CERALOCK®

Where, CL= CL1 CL2

Where, =L= CL1+CL2

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.

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.

1. Stability of Oscillation Frequency

This chapter describes the general characteristics of the basic

oscillation of Fig. 4-1 (page17). Contact Murata for detailed

characteristics of oscillation with specific kinds of ICs and LSIs.

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.

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.

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 the ceramic

resistor is one or two decades faster than a quartz

crystal.

Fig. 5-5 shows comparison of rise time between the two.

4. Starting Voltage

Starting voltage refer to the minimum supply voltage at

which an oscillation circuit can operate. Starting voltage

is affected by all the circuit elements, but it is

determined mostly by the characteristics of the IC.

Fig. 5-6 shows an example of an actual measurement for

the starting voltage characteristics against the loading

capacitance.

1. Application to Microcomputers

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.

CERALOCK® is optimum for a stable oscillation element

for various kinds of microcomputers : 4-bit, 8-bit and

16-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 LSI manufacturers about the

circuit constants, because these constants vary with

frequency and the LSI circuit being used.

Fig. 6-1 to 6-5 show applications to various kinds of

4-bit microcomputers, Fig. 6-6 to 6-8 show application to

8-bit microcomputers, and Fig. 6-9 to 6-10 show

application to 16bit and 32bit microcomputers.
