摘要
详细阐述了 4× 4光开关矩阵的控制及驱动电路的设计。通过分析开关矩阵状态表、状态切换方法及磁保持驱动的特点 ,提出了几种控制驱动的设计方案 ,并讨论了各自的优缺点。最后给出利用打印机接口和通用阵列逻辑的具体实现方案。测试结果表明电路具有良好的性能。
The design of the control and driving circuits for 4× 4 optical switching m atrix is described in detail. Several kinds of configuration schem e are proposed based on the analysis of the m atrix's state table,the m ethod for state switching and the characteristics of magnetic latching driving. Meanwhile the differences among them are dis- cussed. At last a kind of im plem entation of circuits using L PT and Generic Array L ogic is given. The testing results show that the performance of the circuits is good.
