TDA5051AT/C1,512

Overview

The TDA5051AT/C1,512 is a home automation modem IC designed for ASK transmission over the home power supply network. It supports data rates of 600 baud or 1200 baud and operates from a single 5 V supply (4.75 V to 5.25 V). The device features full digital carrier generation, an integrated output power stage with overload protection, and automatic gain control at the receiver input. Key electrical parameters include a typical oscillator frequency of 8.48 MHz, a carrier frequency of 132.5 kHz, and a total supply current ranging from 19 mA in power-down mode to 68 mA in transmission mode. It complies with EN50065-1 standards and is housed in an SO16 plastic package.
