Wired Transceivers & Modems | NCN5151
概览
NCN5151 是一款单芯片集成式从收发器，适用于两线仪表总线 (M-BUS) 从属器件和中继器。NCN5151 重新使用了 NCN5150 的功能，并增加了两种低功耗模式：专用于电表通信系统和无电表 (SCR) 读数的 2 线低功耗模式，以及支持无线应用的 3 线低功耗模式。当在低功耗模式下配置时，收发器将不再充当恒定电流源，以便节省能耗。当配置并以 M-BUS 模式使用时，NCN5151 收发器提供满足规定 M-BUS 物理层要求的欧洲标准 EN 13757-2 和 EN 1434-3 所需的所有功能。它包括了高达 6 个单位负载的可编程功率水平，可通过 3.3 V LDO 稳压器用于外部电路。
