I'm building a project which involves the above mentioned IC. I have the data sheet but i'm still having some difficulty understanding it. If anyone does understand it, could you explain and possibly give a comprehensive circuit diagram of it. Any help will be appreciated.
After all it is a one off project for learning. These chips are still sold as spares / salvageable from scrap radios. Perhaps the OP is not asking for industry, but for a practice of making some gadget. Most people make test and leave at that, to gain experience.
Perhaps, no point is asking them to go for latest chips that are more complicated like PLL and I2C control etc
