| 摘要: | 由於在差模傳輸中，平行線的間距會影響訊號的完整度，尤其，當平行線的間距太小時，會使訊號變得不完整而產生失真，進而影響訊號傳輸的準確性。本文的主要目的是在探討差模傳輸線不同間距所產生對於訊號完整度的影響，並由分析中得到平行線之間距與訊號完整度之最佳結果，在線寬為 10mil 之差模傳輸線時，其平行線之間距至少應為 10mil 以上，亦即平行線之間距至少應為其傳輸線之線寬以上，方能維持訊號之完整性。
As the digital circuits improved speedly and the pulses developed continuously, the electromagnetic interference (EMI) phenomenon becomes 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 interference problem of the gap of differential mode lines and the influence for signal integrity. |
