Default AD1865 and PCM2707

Hi Friends.

Does anybody know hi I connect a AD1865 in the I2S of PCM2707? I think the AD1865 is a very very cool DAC to use in the PCM. And I have then.

Can anybody help me?

Best Regards,
Felipe Navarro

I didn't build this, but the simulation tells it should work perfectly. The DATA is first shifted by 13 bits to match the format for AD1865 (18bit, MSB first). After this it is shifted by 32 bits. This is not necessary, but this way the conversion of left and right chanel will take place at the same time. After that the lines are reclocked in a quad D-type flip-flop (74HC175).

Hi Rookie,

I'm very happy with your post. Thanks a lot for this reply.

In your opinion. This work or this isn't work? I will test it, but in now I haven't a DAC with I2S to test. But in 2 or 3 months, I will have.

Best regards,
Felipe Navarro

E aí mod_evil, beleza?

Where did you get those AD1865? Those should be very nice dacs, they are used on the Audio Note units...

Really hard to get digital audio parts here in Brazil, isn´t it?

Um abraço,
Alexandre

Yes!

This is very hard. I have 2 of these dacs who a Holland Friend have sended to me!

I have many pieces to make the dac, PCM2707 and much of OPA637!

Can you make a PCB for these PCM2707 and a I2S output? If you can, we can make changes... What do you think?

Please contact me!

I have MSN and E-MAIL! The email you can send with the help of this Fórum.
