Description

The ST7538Q is a Half Duplex

synchronous/asynchronous FSK Modem

designed for power line communication network

applications. It operates from a single supply

voltage and integrates a line driver and two linear

regulators for 5V and 3.3V. The device operation

is controlled by means of an internal register,

programmable through the synchronous serial

interface. Additional functions as watchdog, clock

output, output voltage and current control,

preamble detection, time-out, band in use are

included. Realized in Multipower BCD5

technology that allows to integrate DMOS, Bipolar

and CMOS structures in the same chip.
