General description
The TDA5051A is a modem IC, specifically dedicated to ASK transmission by means of the home power supply network, at 600 baud or 1200 baud data rate. It operates from a single 5 V supply.

FEATUREs and benefits
■ Full digital carrier generation and shaping
■ Modulation/demodulation frequency set by clock adjustment, from microcontroller or on-chip oscillator
■ High clock rate of 6-bit D/A (Digital to Analog) converter for rejection of aliasing components
■ Fully integrated output power stage with overload protection
■ Automatic Gain Control (AGC) at receiver input
■ 8-bit A/D (Analog to Digital) converter and narrow digital filtering
■ Digital demodulation delivering baseband data
■ Easy compliance with EN50065-1 with simple coupling network
■ Few external components for low cost applications
■ SO16 plastic package

APPLICATIONs
■ Home appliance control (air conditioning, shutters, lighting, alarms and so on)
■ Energy/heating control
■ Amplitude Shift Keying (ASK) data transmission using the home power network
