摘要
提出了一种大规模光开关阵列驱动控制电路的设计方法,创造性地使用FPGA控制数模转换器和高速开关实现了高电平、低电平可任意调节,通过方案整体设计、电路设计、软件设计相结合的方法,完整介绍了一种新型大规模光开关阵列驱动控制电路的设计原理。试验表明控制电路切换速度小于2 ns。
In order to solve the practical problem between fast speed of optical switch and slow speed of drive control circuit,a design method of driving and controlling circuit for large-scale optical switch array was presented.High level or low level amplitude of the drive and control circuit could be arbitrarily adjusted by using FPGA to control the digital to analog converter and high-speed switch,which was creative.The new design principle of large-scale optical switch array drive control circuit was introduced completely through the combination of overall design,circuit design and software de-sign.Finally,the test showed that the switching speed of the control circuit was less than 2 ns.
