General Description

The AMIS-30585 is a half duplex S-FSK modem and is dedicated for the data transmission on low- or medium-voltage power lines.

The device offers complete handling of the protocol layers from the physical up to the MAC. AMIS-30585 complies with the EN 50065 CENELEC, IEC 1334-4-32 and the IEC 1334-5-1 standards.

It operates from a single 3.3V power supply and is interfaced to the power line by an external power driver and transformer. An internal PLL is locked to the mains frequency (50Hz or 60Hz) and is used to synchronize the data transmission at data rates of 300, 600 and 1200 baud for a 50Hz mains frequency, corresponding to 3.6 or 12 data bits per half cycle of the mains frequency (50Hz or 60Hz).
