On Semi 公司的AMIS-49587是电力线载波(PLC)调制解调器,把模拟调制解调器前端和数字后处理功能集成在单芯片上.它基于ARM7TDMI处理器内核，包含物理接口收发器(PHY)和媒体访问控制器(MAC)层. AMIS-49587采用扩频型移频键控(S-FSK)调制技术，结合精确的滤波，提供长距离电力线的强固低数据率通信，及2,400 bps(波特)的半双工可调节通信速率. AMIS-49587符合IEC1334标准,主要应用于智能电力自动读表及管理、街道照明控制、智能电力插头和建筑物自动化等等。本文介绍了AMIS-49587主要特性,方框图, 发送器方框图, 接收器模拟通路, 50/60Hz抑制滤波器外接元件连接图和典型应用案例框图.
ON Semiconductor’s AMIS−49587 is an IEC1334 compliant power line carrier modem using spread−FSK (S−FSK) modulation for robust low data rate communication over power lines. AMIS−49587 is built around an ARM 7TDMI processor core, and includes the MAC layer.
With this robust modulation technique, signals on the power lines can pass long distances. The half−duplex operation is automatically synchronized to the mains, and can be up to 2400 bits/sec. The product configuration is done via its serial interface, which allows the user to concentrate on the development of the application.
The AMIS−49587 is implemented in ON Semiconductor mixed signal technology, combining both analog circuitry and digital functionality on the same IC.
