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. P17E.pdf 2012.10.31

1 Characteristics and Types of CERALOCK®
- 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 ᶃHigh 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 –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. ᶄ Small configuration and light weight: The ceramic resonator is half the size of popular quartz crystals. ᶅ 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. ˙Vibration Mode and Frequency Range Frequency (Hz) Vibration Mode Flexural mode Length mode Area expansion mode Radius vibration Shear thickness mode Thickness expansion mode Surface acoustic wave 1k 10k 100k 1M 10M 100M 1G ˙Characteristics of Various Oscillator Elements Name Symbol Price Size Adjust- ment Oscillation Frequency Initial Tolerance Long-term Stability LC lower cost Big Required ±2.0% Fair [Note] :ˡˠshow the direction of vibration CR lower cost Small Required ±2.0% Fair Quartz Crystal Expen- sive Big Not required ±0.001% Excellent Ceramic Resonator Inexpen- sive Small Not required ±0.5% Excellent P17E.pdf 2012.10.31

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 FrʽFʽFa, the impedance is given as Z=Re+j ωLe (Leʾ0) as shown in Fig. 2-4, and CERALOCK® should work as an inductance Le (H) having the loss Re (Ω).

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.

(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 Ὑ, the resonance frequency is Fr, the speed of sound waves travelling through piezoelectric ceramics, and the wavelength is λ. Fr. Ὑ = Const. (frequency constant, Fr.t for the thickness) λ = 2 Ὑ C = Fr.λ = 2Fr. Ὑ As seen in the above formula, the frequency constant determines the size of the resonator. (Note 2) In Fig. 2-3, when resistance R 1 is omitted for simplification, the impedance Z (ω) between two terminals is expressed by the following formula. Fig. ᶗ

Basic Oscillation Circuits Generally, basic oscillation circuits can be grouped into the following 3 categories. ᶃ Use of positive feedback ᶄ Use of negative resistance element ᶅ 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, C L1 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. Loop Gain G = αɾβ ʾ1 Phase Amount (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.

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 Fig. 2-9 shows the actual measuring circuit, and an example of UIFmeasuring result is shown in Fig. 2-10.

In the figure, Ri stands for input impedance, R0 stands for output impedance and stands for current amplification rate. When the oscillation circuit in Fig.2-6 is expressed by using the equivalent circuit in Fig.ᶙ it becomes like Fig. ᶚ. Z 1, 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.ᶚ. As i 1 ≠ 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®
- 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”.) Electrical Specifications of MHz Band Lead CERALOCK® (CSTLS Series) Electrical specifications of CSTLS series are shown in the tables.

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 C L1 and CL2 provide the phase lag of 180°. The proper selected value depends on the application, the IC used, and the frequency.

4 Application to Typical Oscillation Circuits
- 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. fosc.=Fr 1+ (4-1)C1 C0+CL Fig. 4-2 C-MOS Standard Circuit VDD Rf 34 7 RdCERALOCK® CL1 CL2 Output IC:TC4069UBP(TOSHIBA) Item Part Number Frequency Rage V DD CL1 Circuit Constant CSTLS˘G53 3.40—10.00MHz +5V (15pF) CL2 (15pF) Rf 1MΩ Rd P17E.pdf 2012.10.31

Therefore, please review our product specifications or consult the approval sheet for product specifications before ordering. 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 (C L) 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.

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 (C L1, 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.

5 Characteristics of CERALOCK® Oscillation Circuit
- 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.
