Product Summary
The ST7538P 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 functions of ST7538P as watchdog, clock output, output voltage and current control, preamble detection, time-out, band in use are included.
