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.
