22、7 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ PIEZOELECTRIC, DIELECTRIC AND ELECTROSTATIC OSCILLATORS OF ASSESSED QUALITY Part 1: Generic specification FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechn
23、ical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
24、 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, gov
25、ernmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decision
26、s or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for internati
27、onal use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order
28、to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearl
29、y indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bod
30、ies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, propert
31、y damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in thi
32、s publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or
33、 all such patent rights. International Standard IEC 60679-1 has been prepared by IEC technical committee TC 49: Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control, selection and detection. This fourth edition cancels and replaces the third edition publ
34、ished in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the title has been changed; b) additional matters related to oscillator using SAW or MEMS resonator in “Terms, definitions and gene
35、ral information“ have been included; c) measurement methods of IEC 60679-1:2007 have been removed (they will be moved to IEC 62884 series); IEC 60679-1:2017 IEC 2017 5 d) the content of Annex A has been extended; e) a new term and definition DIXO (Digital interfaced Crystal Oscillator) has been adde
36、d; f) a new term and definition SSXO (Spread Spectrum Crystal Oscillator) has been added; g) Annex D has been added. The text of this standard is based on the following documents: FDIS Report on voting 49/1229/FDIS 49/1233/RVD Full information on the voting for the approval of this International Sta
37、ndard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 60679 series, published under the general title piezoelectric, dielectric and electrostatic oscillators of assesse
38、d quality can be found on the IEC website. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated at the time of the next edition. The committee has decided that the contents of this document will remain unchanged
39、until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later dat
