The quartz wafer inside is cut and shaped to give a resonant frequency within the speciied limits. IQD's quartz crystal part numbers all contain the code XTAL. The electrical parameters are given on the speciication to facilitate the correct circuit design. Further guidance can be found in the Application Notes chapter of this book. Our Application Support team can also provide assistance if required; please contact one of our sales ofices for this support. The limits given in the following speciications are indicative of the standard crystal design, in the event that a speciication is needed which is outside the standard crystal designs offered please contact our Sales team. A typical quartz crystal speciication reads like this: 10.0MHz 12SMX-B 50/50/-20 to 70C/20/ FUND TE The data in the example above is translated in the following order Frequency Model & Variant Frequency Tolerance @ 25C 3 lead base Fitted insulator Top wire Cropped leads Insulating sleeve Formed leads Frequency Tolerance The cost of manufacture depends partly on the accuracy required at reference temperature (which in the case of the AT-cut crystal, is usually 25C). Where high initial accuracy is important the additional manufacturing cost should be weighed against the cost of including a frequency trimming facility within the oscillator circuit design. Frequency Stability Frequency stability is normally speciied as a frequency variation over a deined operating temperature range with respect to the frequency at reference temperature. The temperature ranges are deined for each crystal in the relevant data sheet. However the majority of crystals will continue to operate quite satisfactorily outside the temperature range for which they are speciied, but with a possible degradation in the value of frequency stability. Under normal conditions this will not damage the crystal. A crystal designed for operation over a restricted operating temperature range, (such as from 0 to 50C) generally has a better frequency stability over that range than one designed for operation over a wide operating temperature range. Therefore it is important not to over specify the temperature range, as doing so will result in inferior performance for the same or greater cost; or greater cost for the same or inferior performance. Frequency Stability (over operating temperature range) Operating Temperature Range Load Capacitance Overtone Additional Text Code Frequency Frequency is normally speciied in kilohertz (kHz) up to 999.999kHz and in megahertz (MHz) from 1.0MHz. All our computer-generated transaction documents follow this standard convention automatically. The frequency should be described to seven signiicant igures. If seven signiicant igures are not used, we assume that any igure that might follow those given may be taken as zero. Thus a frequency given as 16.6MHz will be taken as 16.60, not 16.66667. Some speciiers extend the use of kHz to all crystals operating in fundamental mode, reserving MHz for overtones, this method is not used by IQD. To minimise the possibility of misunderstanding it is best to use the standard method and specify fundamental or overtone mode separately. Please contact a sales ofice for details of developed frequencies. Model Before manufacture of the crystal can start, the model must be deined. Each model covers a frequency range which is deined in the relevant speciication. The model information should also cover any mechanical variants required such as a top wire or cropped leads. For leaded versions, the following variants for example are www.iqdfrequencyproducts.com available for most crystals, either singly or in some cases, in combination: 20 Generalised frequency vs temperature curves for the AT-cut crystal types are illustrated below. These indicate that, without compensation, a crystal speciied for operation over a wide frequency range will probably have an inferior performance over a narrower range than one whose design was optimised for the narrower range. The angle of cut of the quartz blank from its quartz stone determines which curve will be followed; the chosen angle being subject to its own tolerance. Thus, since manufacturing cost is tolerance-dependent it is wise not to specify a wider operating temperature range than is actually needed unless some sacriice of stability, or an increase in cost, can be accepted. Typical Frequency vs Temperature Curves for various angles of AT-cut crystals Additional Text Code If the product is non-standard, the letter `T' and/or `E' will appear at the end of the product speciication.

All dimensions are shown in mm and are nominal unless otherwise stated. 20ppm Marking Due to the small size of modern SMT devices many components are now not marked with any customer readable information beyond the pad 1 denominator. In these cases the marking will be production speciic data. Operating Temperature Ranges The standard operating temperature ranges for a crystal are: 0 to 50C -40 to 85C -10 to 60C -55 to 105C -20 to 70C -55 to 125C -30 to 80C Load Condition The characters `SR' are used to denote calibration of the crystal at series resonance. If it is to be calibrated at load resonance the characters represent the circuit load capacitance in pF. Overtone Order Quartz crystals resonate in speciic "modes" depending upon the frequency in question and oscillator circuit coniguration in which it is used. The main mode of operation is called "fundamental". i.e. a 10MHz crystal vibrates at a frequency of 10MHz However for high frequency use, quartz crystals can be made to operate at odd multiples of its fundamental frequency. These multiples are termed "overtones" and are denoted by their multiple as: 3rd , 5th, 7th, 9th. e.g. a 10MHz crystal can be made to operate at its 3rd overtone which is approximately 3 times its fundamental frequency. If an overtone mode crystal is chosen then the circuit design must include the relevant components required to suppress the fundamental mode of operation to ensure oscillation at the intended frequency. Where there is a cross-over band in the modes available, the mode required must be speciied when ordering. For general use and simplicity of circuit design we recommend that fundamental mode be chosen where possible. 21 www.iqdfrequencyproducts.com QUARTZ CRYSTALS Packaging Codes
