摘要: 由於數位電路的快速發展及時脈的不斷提升，電磁干擾的現象愈來愈受到重視。差模傳輸的電磁干擾現象比共模傳輸小，所以很多高速傳輸已經漸漸地改用差模的方式來傳輸。在差模傳輸中，一個訊號需要用到兩條相位完全相反訊號線來傳輸，然而在某些情況下這兩條線訊號沒有完全同步地相位相反，那麼就會產生共模的干擾訊號，當干擾提升時，甚至會影響訊號的完整度。本文的主要目的是在探討非等長的差模傳輸線所產生的相位問題及對於訊號完整度的影響。
As the digital circuits improved speedly and the pulses developed continuously, the electromagnetic interference (EMI) phenomenon is becoming increasingly popular. The EMI of the differential mode line is smaller than that of the common mode line so that many high speed circuits have been gradually utilizing the differential mode. In the differential mode line, a signal needs to adopt two transmission lines of the diametrically opposed phase, but the signals of these lines don’t have complete synchronization out of phase under same conditions. Accordingly, the interference signals of the common mode are brought and even affect the signal integrity. This paper probes into the brought phase problem of the unfixed-length differential mode lines and the influence for signal integrity.
