ST7540 Description
The ST7540 is a Half Duplex synchronous/asynchronous FSK Modem designed for power line munication 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.
