STMicroelectronics ST7538Q

The ST7538Q is a Half Duplex synchronous/asynchronous FSK Modem Integrated 3.3V voltage regulator (up to 50mA) designed for power line communication network with short circuit protection applications. It operates from a single supply 3.3V or 5V digital supply voltage and integrates a line driver and two linear regulators for 5V and 3.3V. The device operation 8 programmable transmission frequencies is controlled by means of an internal register, Programmable baud rate up to 4800BPS programmable through the synchronous serial Receiving sensitivity up to 250µVrms interface.
