Product data sheet
1. 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.
2. 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
3. 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
