27、RYSTAL CONTROLLED OSCILLATORS OF ASSESSED QUALITY Part 6: Phase jitter measurement method for quartz crystal oscillators and SAW oscillators Application guidelines FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national

28、electrotechnical 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 Spe

29、cifications, 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. Intern

30、ational, governmental 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 for

31、mal decisions 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 f

32、or international 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.

33、4) In order 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 sha

34、ll be clearly 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 certi

35、fication bodies. 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 inj

36、ury, property 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

37、cited in this 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 identi

38、fying any or all such patent rights. International Standard IEC 60679-6 has been prepared by lEC technical committee 49: Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control, selection and detection. This standard cancels and replaces IEC/PAS 60679-6 pub

39、lished in 2008. This first edition constitutes a technical revision. 60679-6 IEC:2011 5 The text of this standard is based on the following documents: FDIS Report on voting 49/935/FDIS 49/944/RVD Full information on the voting for the approval of this standard can be found in the report on voting in

A list of all parts of the IEC 60679 series, published under the general title Quartz crystal controlled oscillators of assessed quality, can be found on the IEC website. The committee ha

41、s decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or

42、amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 60679-6 IEC:2011 INTRODUCTION The s

43、tudy of phase jitter measurement methods was conducted in accordance with the agreement during the IEC TC 49 Berlin international meeting in 2001. At this meeting, the decision was made that Japan should assume the responsibilities of this study. Then, the technical committee of the Quartz Crystal I

44、ndustry Association of Japan (QIAJ) proceeded with this study. This study was substantially conducted during the years 2002 to 2005 and can be referred to as the first stage of the study. The second stage is being continued at present. Phase jitter has become one of the essential measurement items b

45、y digitization of electronic devices. However, theoretically, some ambiguity is still left in the phase jitter. Since no standard measurement method is proposed, suppliers and customers may be mutually exposed to a risk which could cause enormous economic losses. To avoid this risk, this document pr

46、ovides a standard, based on the study results during the first stage, for each company of QIAJ members to avoid anxiety as to the measurement of the phase jitter and for the purpose of giving guidance without any mistakes. In this standard, a recommendation to make r.m.s. jitter a measurement object

47、 is presented. The reason why this recommendation is submitted is because the oscillators resulting in ultra- low amount of jitter are targeted as the object to be measured. Oscillators are analogue-type electronic devices. Their sine wave output signals are more favourable than the signals obtained

48、 by electronic systems. Moreover, the output is utilized as the reference clock of the measurement equipment, leading to a situation in which the amount of phase jitter is shown to be smaller than the amount of phase jitter of the measurement equipment. Accordingly, this may give the impression that

49、 the measured amount of phase jitter is not from the oscillators but rather the amount of phase jitter generated by the measurement equipment, or the measurement system. Therefore, when adopting the amount of other phase jitters as the measurement items, a recommendation is presented to select measurement equipment and a measurement system capable of being verified and confirmed sufficiently, contractually det
