Package: SO16 plastic type

Manufacturer: NXP Semiconductors.


TDA5051 datasheet



The TDA5051 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 :

1. Full digital carrier generation and shaping

2. Modulation/demodulation frequency set by clock adjustment, from microcontroller or
on-chip oscillator

3. High clock rate of 6-bit D/A (Digital to Analog) converter for rejection of aliasing

4. Fully integrated output power stage with overload protection

5. Automatic Gain Control (AGC) at receiver input

6. 8-bit A/D (Analog to Digital) converter and narrow digital filtering

7. Digital demodulation delivering baseband data

8. Easy compliance with EN50065-1 with simple coupling network

9. Few external components for low cost applications



1. Home appliance control (air conditioning, shutters, lighting, alarms and so on)

2. Energy / heating control

3. Amplitude Shift Keying (ASK) data transmission using the home power network
