P17E14.pdf 04.8.24 Introduction Ceramic resonators (CERALOCK(R)) 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(R) can be used as the timing element in most microprocessor based equipment. In the future, more and more applications will use CERALOCK(R) because of its high stability nonadjustment 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(R) and will assist you in applying it effectively. * CERALOCK(R) is the brand name of these MURATA products. !Note Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this PDF catalog to prevent smoking and/or burning, etc. This catalog has only typical specifications.

P17E14.pdf 04.8.24 1 Characteristics and Types of CERALOCK(R) 1. General Characteristics of CERALOCK(R) 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(R). 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 +80C 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(R) 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. !Vibration Mode and Frequency Range Frequency (Hz) Vibration Mode 1 Flexural mode 2 Length mode 3 Area expansion mode 4 Radius vibration 5 Shear thickness mode 6 Thickness expander mode 7 Surface acoustic wave [Note] : ,./ show the direction of vibration 1 1k 10k 100k 1M 10M 100M 1G !Characteristics of Various Oscillator Elements Name Symbol Price Size Oscillation Adjust- Frequency Long-term Initial ment Stability Tolerance LC Inexpensive Big Required 2.0% Fair CR Inexpensive Small Required 2.0% Fair Quartz Crystal Expensive Big Not 0.001% Excellent required Ceramic Resonator Inexpensive Small Not required 0.5% Excellent 2 !Note Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this PDF catalog to prevent smoking and/or burning, etc. This catalog has only typical specifications.

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 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.

P17E14.pdf 04.8.24 Principles of CERALOCK(R) 2 The table on this page shows comparison for the equivalent constants between CERALOCK(R) 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(R). 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.

P17E14.pdf 04.8.24 2 Principles of CERALOCK(R) 2 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 . Fr*r = Const. (frequency constant, Fr*t for the thickness) = 2r C = Fr* = 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 () between two terminals is expressed by the following formula. 1 ( jL1+ 1 ) jC0 jC1 Z () = 1 + ( jL1+ 1 ) jC0 jC1 j ( L1 - = 1) C1 1 + C0 - 2 C0L1 C1 1 = r, Z (r) =0 L1C1 1 = a, Z (a) = C0C1L1/(C0+C1) When = When = Therefore from =2F, Fr = r/2 = 2 2 1 L1C1 1 = Fr C0C1L1/(C0+C1) 1+ C1 C0 r= / 2 Fa = a/2 = Amplitude Range of Standing Wave L1 C1 (Min.Amplitude) (Max.Amplitude) C0 Fig. 1 Fig. 2 12 !Note Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this PDF catalog to prevent smoking and/or burning, etc. This catalog has only typical specifications.

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.)

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 = * U1 Phase Amount = 1 + 2 = 360xn (n = 1, 2, ***) (2-6) In Colpitts circuit, an inverter of 1 = 180 is used, and it is inverted more than 2 = 180 with L and C in the feedback circuit.

Electrical Specifications The frequency stability of CERALOCK(R) is between that of crystal and LC or RC oscillators. Temperature stability is 0.3 to 0.5% against initial values within -20 to +80C. The initial frequency precision is 0.5% for standard products. The frequency of the standard CERALOCK(R) is adjusted by the standard measuring circuit, but the oscillation frequency may shift when used in the actual IC circuit.

P17E14.pdf 04.8.24 4 Applications of Typical Oscillation Circuits As described in Chapter 2, the most common oscillation circuit with CERALOCK(R) is to replace L of a Colpitts circuit with CERALOCK(R). 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 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 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.

Therefore, you are requested to approve our product specifications or to transact the approval sheet for product specificaions before ordering. P17E14.pdf 04.8.24 4 Application to Typical Oscillation Circuit Oscillation frequency fosc. in this circuit is expressed approximately by the following equation. fosc.=Fr 1+ C1 C0+CL (4-1) Where, Fr=Resonance frequency of CERALOCK(R) Where, C1 : Equivalent series capacitance of Where, C1 : CERALOCK(R) Where, C0 : Equivalent parallel capacitance of Where, C1 : CERALOCK(R) CL1 * CL2 Where, CL= Where, = L= CL1+CL2 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. 4 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(R) (C-MOS specifications) is adjusted by the circuit in Fig. 4-2.

P17E14.pdf 04.8.24 Application to Typical Oscillation Circuit 4 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 unbuffered 74HCU series and the 74HC series with buffers. The 74HCU system is optimum for the CERALOCK(R) 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. 4 Frequency Rage Circuit Constant CL1 330pF 220pF 150pF 100pF (47pF) 30pF 15pF 5pF CL2 330pF 220pF 150pF 100pF (47pF) 30pF 15pF 5pF Rf 1M 1M 1M 1M 1M 1M 1M 1M Rd 5.6k 5.6k 5.6k 5.6k 680 0 0 0 Item VDD (+5V) Part Number 14 IC : TC74HCU04 (TOSHIBA)* 1 Rf CERALOCK(R) Rd Output CL1 CL2 23 4 7 0375~0429kHz 0430~0699kHz CSBLA- E (J) 0700~0999kHz 1000~1250kHz CSTLS- G56 CSALS- X55 03.40~10.00MHz 16.00~19.99MHz 20.00~25.99MHz 26.00~70.00MHz 60.01--70.00MHz : SN74AHCU04 CSALS- X53 CSALS- X51 Fig. 4-3 H-CMOS Standard Circuit 23 !Note Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this PDF catalog to prevent smoking and/or burning, etc. This catalog has only typical specifications.

Influence of load capacitance (CL1, CL2) on the oscillation frequency is relatively high, as seen in formula (4-1) (P.22). 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.

P17E14.pdf 04.8.24 Characteristics of CERALOCK(R) Oscillation Circuit 5 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(R), 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.

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(R) is now widely used as well, because they require no adjustment and have superior stability over the older type circuit.

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.
