ST7538Q

FSK power line transceiver

General features

■ Half duplex frequency shift keying (FSK)

transceiver

■ Integrated power line driver with programmable

voltage and current control

■ Programmable interface:

– Synchronous

TQFP44 Slug Down

– Asynchronous

■ Single supply voltage (from 7.5 up to 12.5V)

■ Very low power consumption (Iq = 5mA)

Description

■ Integrated 5V voltage regulator (up to 50mA)

The ST7538Q is a Half Duplex

with short circuit protection

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

■ Integrated 3.3V voltage regulator (up to 50mA)

with short circuit protection

■ 3.3V or 5V digital supply

■ 8 programmable transmission frequencies

■ Programmable baud rate up to 4800BPS

■ Receiving sensitivity up to 250µVrms

■ Suitable to application in accordance with EN

50065 CENELEC specifications

■ Carrier or preamble detection

■ Band in use detection

technology that allows to integrate DMOS, Bipolar

and CMOS structures in the same chip.

■ Programmable 24 or 48 bit register with

security checksum

■ Mains zero crossing detection and

synchronization

■ Watchdog timer

■ Output voltage freeze

■ 8 or 16 bit header recognition

■ UART/SPI host interface

■ ST7537 compatible
