Sales Briefcase
  • 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.

    Key Features

    • Programmable baud rate up to 4800BPS
    • ST7537 compatible
    • 8 programmable transmission frequencies
    • UART/SPI host interface
    • Suitable to application in accordance with EN 50065 CENELEC specifications
    • Receiving sensitivity up to 250µVrms
    • Band in use detection
    • Carrier or preamble detection
    • Mains zero crossing detection and synchronization
    • Programmable 24 or 48 bit register with security checksum
