DESCRIPTION

The ST7538 is a Half Duplex synchronous/asyn-

chronous FSK Modem designed for power line

communication network applications. It operates

from a single supply voltage and integrates a line

driver and a 5V linear regulator. The device oper-

ation is controlled by means of an internal register,

programmable through the synchronous serial in-

terface. Additional functions as watchdog, clock

output, output voltage and current control, pream-

ble detection, time-out, band in use are included.

Realized in Multipower BCDV technology that al-

lows to integrate DMOS, Bipolar and CMOS struc-

tures in the same chip.
