Hi;

I want to design fm transmitter using si4713. But in digital input, i have problems. Si4713 use 3 pins for digital input DIN, DFS and DCLK. I will use AES/EBU input via XLR connector. How shoud i do the connections between XLR and si4713?

Thanks in advance

You need to decode the AES/EBU signal to one of the raw digital audio format described in the Si4713 datasheet under 5.4. Digital Audio Interface, e.g. I2S. This can be done in a CPLD, if the sample rates are matching. Possible sample rate conversion needs a higher digital signal processing effort.

Fistly, thanks for reply..
In si47xx EVB user manuel, CS8427-CZ was used for SPDIF and AES3 translator. Besides codec(WM8731) and octal buffer (74LCX541) were used. I only use AES digital input. How can I do this decoding process? only CS8427 is enough for decoding?
