DESCRIPTION
The ST7536 is a half duplex synchronous FSK MODEM designed for power line communication network applications.
It operates from a dual power supply +5V and -5V, and requires an external interface for the coupling to the power line. It offers two programmable data rate with two programmable channels each.
