Home automation modem
Product specification
TDA5051
FEATURES
• Full digital carrier generation and shaping
• Modulation/demodulation frequency set by clock
adjustment, from microcontroller or on-chip oscillator
• High clock rate of 6 bits D/A (Digital-to-Analog)
converter for rejection of aliasing components
• Fully integrated output power stage with overload
protection
• Automatic gain control at receiver input
• 8-bit A/D 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
• ASK (Amplitude Shift Keying) data transmission using
the home power network.
GENERAL DESCRIPTION
The TDA5051 is a modem IC, specifically dedicated to
ASK transmission by means of the home power supply
network, at 600 or 1200 baud data rate. It operates from a
single 5 V supply.
