摘要
采用0.35μm CM O S工艺设计了用于光纤传输系统的低功耗16∶1复接器,实现了将16路155.52M b/s数据复接成一路2.5G b/s的数据输出的功能。该复接器以混合结构形式实现:低速部分采用串行结构,高速部分采用树型结构。具体电路由锁存器、选择器及分频器组成,以CM O S逻辑和源极耦合逻辑(SCL)实现。用Sm art SP ICE软件进行仿真的结果显示:在3.3V供电时,整体电路的复接输出最高工作速度可达3.5G b/s,功耗小于300mW。
A low power 16 : 1 MUX (multiplexer) for optical-fiber-transmission system designed with 0.35vm CMOS technology is presented in this paper, it can realize the function of 16 data inputs of 155.52Mb/s to 1 data output of 2.5Gb/s. The MUX is constructed in the combined style of serial-type architecture in low speed part and tree-type in high speed part. The concrete circuits are composed of latches, selectors and frequency dividers. They are implemented with CMOS logic and source coupled logic (SCL). The simulation of the MUX in Smart SPICE shows that the highest speed of the output can reach 3.5Gb/s and its power dissipation is less than 300mW under 3.3V power supply.
