Product specification
TDA5051A
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 A/D (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 Analog) 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.
GENERAL DESCRIPTION
The TDA5051A 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.

Notes
1. Frequency range corresponding to the EN50065-1 band. However, the modem can operate at any lower oscillator
frequency.
2. The minimum value can be improved by using an external amplifier, see application diagrams Figs 22 and 23.
