ST7538 - ST Microelectronics

ST7538 POWER LINE FSK TRANSCEIVER

The ST7538 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 a 5V linear regulator. The device operation is controlled by means of an internal register, programmable through the synchronous serial interface. Additional funct.

Features

regulator. 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 BCDV technology that allows to integrate DMOS, Bipolar and CMOS structures in the same chip. s s s s s s s s BLOCK DIAGRAM DVdd AVdd DVss AVss TEST1 TEST2 TEST3 BU RxFo CD/PD CARRIER DETECTION TEST BU AGC RxD CLR/T PLL DIGITAL FILTER FSK DEMOD IF FILTER FILTER AMPL RAI SERIAL INTERFACE REG/DAT.
