A little help with TDA5051 PLZ ?

[Terminator Electricity]

how to connect tda5051

Hi, Has anyone worked before with TDA5051 ?

I have used the minimal circuit to connect the device ,, it didn't work .. I have tried it using decoders and encoders ,, didn't work,, used it even with manual 1's and 0's to the data_in ,, still didn't work and the data wasn't delivered to the other side ..

Has anyone had problems with the simple circuit the datasheet provided with the TDA5051 ? (without isolation ,, nor improved sensitivity)

Thanks ..

Hi

First check for power applide to the circuit - remember to work with isolation transformaer

2nd whether the first section OK check and measure the oscillator and the oscillator frequency

All the best
