Wired Transceivers & Modems | AMIS-42770
概览
控制器局域网络 (CAN) 是一种串行通信协议，支持分布式实时控制和具有高安全等级的复用。基于 CAN 网络的典型应用为汽车和工业环境。AMIS-42770 双 CAN 收发器是最多两个物理总线和协议控制器之间的接口，用于多个总线处不同电子设备之间的串行数据交换。它可以用于 12 V 和 24 V 系统。该电路包含以下块： - 两个差分线路发射器 - 两个差分线路接收器 - CAN 协议处理器的接口 - 扩展 CAN 总线的接口 - 包括中继器功能和反馈抑制的逻辑块 - 高温关断电路 (TSD) 由于接收器输入较宽的共模电压范围，AMIS-42770 能够达到出色的电磁灵敏度 (EMS)。与之相似，通过输出信号的卓越匹配，可以实现极低的电磁辐射 (EME)。
