Here, C0, which is commonly known as the shunt capacitance, comprises an inter-electrode static capacitance to which the inter-terminal stray capacitance is added. L1 and C1 are the equivalent constants of the quartz crystal unit viewed as an electrical and mechanical oscillation system. Since both constants are determined by such factors as the type of cut, cutting angle, dimensions of the crystal piece, and construction of the electrodes, and are thus reproducible, quartz crystal units, can be manufactured to high precisions. R1, which denotes oscillation loss, is governed by such conditions as the cutting, mounting, and dimensions of the quartz crystal. L1 : Motional inductance C1 : Motional capacitance R1 : Motional (Series) resistance C0 : Shunt capacitance The electrical equivalent circuit, composed of L1, C1, R1 and C0, all of which are correlated, may be expressed by the following equation. f0 1 Shown below are some equations by which the performances of quartz crystal units are expressed. 1 Q 2f0C1 R1 C0 ratio) (Capacitance C1 2f0L1 R1 L1 C1 C0 R1 3

29 HANDLING INSTRUCTIONS The following instructions and information are provided for the purpose of having the user understand the proper way to handle the Citizen crystal products to prevent problems prior to use and enhance the reliability of equipment to which they are applied. I. When dropped by mistake: < All products > The crystal products are designed and manufactured to resist physical shocks. However, in the event the crystal is subjected to excessive impact such as being dropped onto the floor or giving shocks during mounting. Need to make sure its satisfactory performance before using it. II. Soldering: < Lead Type products > (1) Lead wires should be soldered within 3 seconds with the iron heated to a temperature no higher than 380 C. (2) In solder-dip mounting, it should be within 10 seconds with a temperature no higher than 260 C. And beware not to heat the whole crystal unit in the dip mounting process. Mounting in upright bearing is recommendable (prevent heat conduction directly to the body of a crystal unit). (3) Heating the whole crystal unit, for example, in a reflow oven may deterioration of the performance. Because the holder is quite small and it is sealed by solder material with press sealing so that such reflow process not allowed to be proceeded. < SMD Type products > (1) Eutectic solder (2) Pb free solder III. Bending Lead: < Cylinder Type products > (1) When the lead of cylinder type crystal units need to be bent, leave more than 1.5mm (3.0mm is recommendable) of lead from the case in order to prevent from occurrence of any cracks of the hermetic seal glass at the root of the lead and use a jig for bending if possible. (2) When bending the lead of cylinder type crystal units, do not scrape off the solder plating from the lead surface. IV. Mounting: < Cylinder Type products > (1) Soldering on the body of the cylinder type crystal unit must be strictly avoided due to deteriorate the characteristics or damage the products. Rubber adhesive is recommended. 1.5mm Min. (2) When the lead needs to be bent by hand, follow the next instructions. Hold the body of the Cylinder type crystal unit in fingers. Pick at the part with tweezers, which you intend to bend. There should be more than 1.5mm (3.0mm is recommendable) from the body case. Bend the lead 90 by tweezers without pulling the lead strongly. If pulling the lead strongly may cause any cracks of the hermetic seal glass at the root of the lead and may cause the airtightness and the characteristics to deteriorate. 24
30 < SMD Type products > When using an automatic loading machine, test and confirm to cause no damage to the crystal products before mounting. Bending the circuit board in the process of cleaving boards after mounting and soldering crystal products may cause peeling off the soldering or package cracks by mechanical stress. Please be sure that the layout of crystal products position is on the less stressed and the cleaving process is under less stressed for the crystal products. < Crystal Oscillators > Please be sure to confirm that the pin location is proper with electric wiring on the circuit board prior to mounting the crystal oscillators. Mounting to the wrong pin position will cause malfunction and damage to the crystal oscillator and the circuit board. V. Cleaning: < All products > (1) Crystal products may be affected and destroyed at worst by ultrasonic cleaning. Please be sure to check if your cleaning process affects any damage to crystal products prior to use. (2) Some kind of cleaning fluid may cause any damage to crystal products. Please be sure to check suitability of the cleaning fluid in advance. VI. Thermal shock: < Crystal Oscillators > Repetitive rapid changes with a great amplitude in temperature may cause deteriorate the crystal unit and break the wires inside the package. The condition must be avoided. IX. Power supply lines: < Crystal Oscillators > Line impedance of a power supply should be as low as possible. To maintain stable operation, power supplies to the Crystal Oscillator should have by-pass capacitor (0.01µF ~ 0.1µF). Place the capacitor as close as possible to the Crystal Oscillator supply pins (VDD and GND). Supply lines (VDD, GND) should be as wide as possible. X. Output line: < Crystal Oscillators > To reduce the line impedance of the Output line and reduce the electromagnetic radiation, output load should be installed as close as possible to the Crystal Oscillator. XI. Input line: < Crystal Oscillators > Input pin (OE) is pulled up with an internal resister, but if it is not used, connect it to VDD. XII. Storage: < All products > Storage of Crystal products under higher temperature or high humidity for a long term may affect frequency stability or solderability. Please store the Crystal products under the normal temperature and humidity without exposing to direct sunlight and dew condensation, and avoid the storage of Crystal products for more than 6 months, and mount them as soon as possible after unpacking. VII. Static electricity: < Crystal Oscillators > Excessive levels of electricity may cause damage of IC inside of a Crystal oscillator even if an anti static electricity protection circuit is provided in the circuit board. Please be sure to use conductive packing materials and transport containers, and use the soldering gun and the measuring circuit free from high-voltage leakage and provide grounding connection while using crystal oscillators. VIII. Noise: < Crystal Oscillators > Applying excessive levels of extraneous noise to power supply or input pin may cause latch-up or spurious phenomenon, which results in malfunction and breakdown. Do not permit any objects, which emit a high level of noise in a location near the Crystal Oscillator. 25
31 PRECAUTIONS IN OSCILLATION CIRCUIT DESIGN To utilize Crystal units characteristics fully, is necessary to design a oscillation circuit with optimal conditions. Based on Citizen's experience accumulated over the year, Citizen offers such service as checking the oscillation circuit designed by a customer with regard to items mentioning following to ensure optimal matching between the crystal units and the oscillation circuit. The results of investigation with regard to items will be reported to the customer as Citizen's "Circuit Investigation Report". 1. MOS Fundamental Crystal Oscillation Circuit CL : Load capacitance -R : Negative resistance Le : Effective Inductance Re : Effective resistance Rf Crystal unit Oscillation Circuit 5. Frequency-Voltage coefficient Represents the rate of frequency change against variations in the supply voltage. The cause of frequency changing by the power supply variation attributes to factors on the oscillation circuit side (especially IC) than the Crystal unit. It is normally desirable to keep within ±5ppm in the rate of frequency change against ±10% variation in the supply voltage. 6. Frequency tolerance over operating temperature range Represents the rate of frequency change against various in operating temperature. There may be a large difference between the oscillation circuit and the crystal unit in Frequency tolerance over operating temperature range. (Example) Frequency tolerance over operating temperature range C1 Xtal Rd C2 If required Le Re CL R f/f ppm 10 Crystal unit MOS Fundamental Crystal Oscillation Circuit 2. Load capacitance (CL) The Load capacitance (CL) refers to an effective external series capacitance in an assuming oscillation circuit that is viewed from the crystal unit side. Resonance frequency will be determined with the Load capacitance and the crystal unit. For this reason, differences in the load capacitance of the oscillation circuit may cause the frequency deviations (result in a different resonance frequency from the required one). Equation of Load capacitance in Oscillation Circuit C1 C2 CL = + CIC + C C1 + C2 External capacitance Internal capacitance of IC Correlation crystal unit and Oscillation Circuit Stray capacitance of PCB 3. Negative resistance (-R) The Negative resistance reflects the allowance and margin for oscillation motility. An insufficient negative resistance may cause unexpected trouble such as No-Oscillation or slow start-up time. 4. Drive Current (i) The drive current refers to the current flows through a crystal unit. An excessive drive current that is applying a crystal unit may cause the following trouble and phenomenon. Increase in the electromagnetic wave noise. Crystal element of T/F breaking off Get worse the characteristics of the crystal unit such as frequency Tolerance, over Operating Temperature Range, Motional resistance (Series resistance) 7. How to Check a margin for oscillation motility To know a margin for oscillation motility should check the negative resistance (-R) of a oscillation circuit. Connect a variable resistor (VR) to the oscillation circuit in series with the crystal unit. To turn down the value resistor of VR from the NO- OSCILLATION in abeyance to the oscillation START-UP. The value shall be the negative resistance (-R) at the oscillation starts up. Adjust value of C1, C2 and Rd as the negative resistance to be 5 times larger than the effective resistance in order to get enough margins for oscillation motility. And to get 10 times of -R to the effective resistance is recommended for equipment that is required the high quality and reliability such as auto-motive etc. C Xtal Rf VR Oscillation circuit for checking -R Rd C2 Oscillation circuit with the Crystal unit 26
