The TDA5051A is a Power Line Modem (PLM) IC, specifically dedicated to ASK
transmission by means of home power line network at 600 baud or 1200 baud data rate.
It operates from a single 5 V supply.
The TDA5051A employs control logic which provides full digital carrier generation and
shaping, a high clock rate of 6-bit D/A (Digital-to-Analog) converter which provides
rejection of aliasing components. The IC contains a fully integrated output power stage
with overload protection. The receiver employs an AGC (Automatic Gain Control), 8-bit
A/D (Analog-to-Digital) converter and narrowband digital baseband filtering and digital
demodulator. The modulation and demodulation frequency is set by clock source from
microcontroller or on-chip crystal oscillator.
Easy compliance with EN50065-1 is afforded with simple coupling networks. Low cost
applications are realized with few external components. The TDA5051A is housed in the
SO16 plastic package.
