Radio Swing. I need find RDS demodulator

Post by mnicolau » 02 Jul 2016 13:27

Hi all,
I need your help, please

My wife has a Skoda Fabia and its autoradio is good.

I'd like have the data, clock and GND for decoding RDS with my computer but I don't see where is the RDS demodulator chip.

Can you help me and tell me where is the demodulator chip?.


Thank you in avanced

Hi just looked at the pictures the SAF7741HV chip shows two RDS CLK and two data outputs pin 48 CLK 1 pin 49 DATA 1 pin 50 CLK 2 pin 51 DATA 2 see link below and download the PDF.

I have no idea if this will work but you will need to find suitable point to solder to I would recommend using 1 k resistors on the CLK/DATA lines as we do with tuners.

Hi!
Can it run only for RDS the XDR I2C with XDR-GTK software?
And a Seeeduino board like http://ukradio.info/GT-XDR/#standalone ?
I'd lije controled by PC viewtopic.php?f=37&t=2776&start=20 but I don't want Broken the radio.
I'm not sure if viewtopic.php?f=37&t=2776&start=20 is working?
Thank you
