I2S implementation




I was attempted to implement I2S connection from my Juli@ to my DAC, it was no sound.

***J3 Pin 1 -> 1724 PSDOUT[0] ( I2S data out) -> AK4358 SDTI1 (I2S data in)

***J3 Pin 5 -> 1724 PSYNC ( I2S Word Clock ) -> AK4358 LRCK (I2S Left/Right Word clock)

***J3 Pin 7 -> 1724 PBCLK ( I2S bit clock out ) -> AK4358 BICK ( I2S bit clock in )

J3 Pin 9 - > Xilinx on the digital board -> AK4358 MCLK ( I2S Master Clock in )

J3 Pin 11 - > Xilinx & AK4114 on the digital board - > AK4358 PCN (Reset)

Those with asterisk were the signal i tapped and directly feed into my DAC's CS8420 at pin 16,17,18 and both juli@ and dac ground.

I am not sure what was wrong, do i need to connect the master clock and PDN reset as well?

The wordclock was tapped from the J3 P7. It means using the JulI@ as master and dac as slave.

So the connections still remains by using TUBE SPDIF but with external wordclock SYNC.

Wow. I heard some details i never listen before at the same tracks.
The musical effect was so much better and sound is more accurate in tone.
Hmmm, i have some clue that a good cable with I2S connection could make good sound.
