The text of the CECC specification has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in Briti
7、sh Standards; attention is drawn especially to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Cross-references. The British Standard which implements CECC 00100 is BS 9000 “General req
8、uirements for a system for electronic components of assessed quality” Part 2 “Specification for national implementation of CECC basic rules and rules of procedure”. The Technical Committee has reviewed the provisions of IEC 147, to which reference is made in the text, and has decided that they are a
9、cceptable for use in conjunction with this standard. A related British Standard for IEC 147 is BS 9300 “Semiconductor devices of assessed quality: generic data and methods of test”. Scope. This standard lists the ratings, characteristics and inspection requirements which shall be included as mandato

15、27:37 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS CECC 90301:1985 ii BSI 02-2000 Foreword The CENELEC Electronic Components Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System f
16、or electronic components of assessed quality. The object of the System is to facilitate international trade by the harmonization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. T
17、he components produced under the System are thereby accepted by all member countries without further testing. This specification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized specifications for INTEGR
18、ATED LINE TRANSMITTERS AND/OR RECEIVERS. It should be read in conjunction with the current regulations for the CECC System. At the date of printing of this specification the member countries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway,
19、 Portugal, Spain, Sweden, Switzerland, and the United Kingdom, Preface This blank detail specification (BDS) was prepared by CECC WG9 “INTEGRATED CIRCUITS”. It is based, wherever possible, on the Publications of the International Electrotechnical Commission and in particular on IEC 147: Essential ra
20、tings and characteristics of semiconductor devices and general principles of measuring methods. The text of this BDS was circulated to the CECC for voting in the document indicated below and was ratified by the President of the CECC for printing as a CECC Specification. It is recognized that the lay
21、out proposed cannot apply to all detail specifications based on this document. For example when several similar devices are covered by the same detail specification, it may be convenient to give the limiting values in a table. In accordance with the decision of the CECC Management Committee this spe
22、cification is published initially in English and French. The German text will follow as soon as it has been prepared.

46、0 3.3 Rules of matching In all differential systems it is required to match the characteristic impedance Zo with the output impedance of the transmitter and the input impedance of the receiver. Two methods may be used for this match, called serial resistors method and parallel resistors method; the
47、matching resistors may be integrated on the die. The correct computation of resistors values needed to match the characteristic impedance of the line must take care of transmitter output or receiver input impedances. For the best use of complete transmission system never forget that the common mode
48、characteristic line impedance and differential mode characteristic line impedance may be very different. 3.3.1 Serial resistors method 1) Match of A1/2 line transmitter impedances The matching of specified output voltage line transmitter is described by Figure 5.
