iconductor’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.
