DESCRIPTION

The ST7537HS1 is a half duplex asynchronous

FSK MODEM designed for home automation com-

munication on the domestic electric mains which

complies with the EN 50065-1 CENELEC stand-

ard.

It mainly operates from a 10V power supply and a

5V power supply for the microcontroller digital in-

terface.

It is interfaced to the power line by an external

driver, and a transformer (see Application Sche-

matic Diagram). Its data transmission rate is

2400 bps and its carrier frequency is 132.45kHz.
