Hi, I also got the same tuner having that IC and a companion IC (16 pin) numbers printed are Philips, 5520, J8788, J9704. Can anyone help?
I am looking for tuners having PLL and digital PLL control.

Hai Faithnic,
I identified the other IC easily. It is TSA5520 from Philips. It is a 1.3GHz , I2C controlled PLL.

| Great Matbob! I want to program it through an ATMEGA I2C bus, anyone has any experience?

Hai Faithnic,
I have done it with PIC. Just dig out everthing from the dataaheet. Its not that difficult as it seems.

Hi Matbob,
Can I have a look at your PIC control of the tuner?
Thanks.

Hi Faithnic,
Sorry for the delay. Actually I have implemented an FM receiver using the tuner. I did the coding in a compiler named 'MikroC' for PIC micros. Also I have done a simulation for the circuit using 'Proteus'. I have attached all the files here.
For controlling the freq, etc I used a IR remote with SIRC protocol. Also an LCD is used to display the frequency.
Please look at the comments in the code for any clarifications though it is not commented extensively  .
