数据: DS40MB200 Dual 4-Gbps 2:1/1:2 CML MUX/Buffer With Transmit Pre-Emphasis and Receive Equalization 数据表
DS40MB200器件是双信号调理2:1多路复用器(MUX)和1:2扇出缓冲器,设计用于背板冗余应用。信号调理功能包括连续时间线性均衡(CTLE)和可编程输出预加重,在FR4背板中以高达4 Gbps的速率扩展数据通信。每个输入级都有一个固定均衡器,以减少电路板走线的符号间干扰失真。
所有输出驱动器都有四个可选择的预加重步骤,以补偿长FR4背板的传输损耗,并降低确定性抖动。可以为线路侧和开关侧驱动器独立控制预加重级别。从开关侧输入到开关侧输出的内部环回路径可实现全速系统测试。所有接收器输入均在内部端接100Ω差分终端电阻。所有驱动器内部端接50Ω至V CC 。
