中文摘要 | 網際網路的快速發展,寬頻服務的需求乃大勢所趨,新世代迴路接取系統 ( NGLAS )就是基於此理念所建構,在此我們將經由實作過程累積的經驗, 探討高速背板 匯流排製作時的考慮因素與設計方法:包括高速匯流排的信號準位、傳輸線特性阻抗與終端 電阻之計算、實際佈線時遭遇的問題,譬如佈線路徑、線距,以及如何以工程的觀點來解決 。並以實作為例,說明其製作流程,包括規格要求的擬定、主要晶片的選擇、電路硬體的設 計、控制軟體的撰寫以及測試等。 |
英文摘要 | Internet has been developing fast, the requirements for broadband services are obvious tendencies. The Next Generation Loop Access System (NGLAS) is constructed based on this concept. By means of our experiences in implementation, we will discuss considerations and design algorithm of making high-speed blackplane bus here. it includes the signal levels of high-speed bus, the calculations of characteristic impedance and terminal resistance, the problems of the PCB layout such as the routing path, trace spacing, and how to solve these problems from engineering view. And we also take an illustration to describe the flow of the implementation including the draft of the specifications, the choice of the main chips, the hardware design, the control software, and test. |
