DESCRIPTION

· The TDA5051A is a modem IC designed for ASK transmission over home power supply networks, supporting data rates of 600 baud or 1200 baud. It operates on a single 5 V supply.

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-bit D/A converter for aliasing component rejection
· Fully integrated output power stage with overload protection
· Automatic Gain Control (AGC) at receiver input
· 8-bit A/D 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, etc.)
· Energy/heating control
· Amplitude Shift Keying (ASK) data transmission using the home power network
