Default I2S into a 1865 chip?

I have the DAC END which is the same as the Audio Note. I want to try I2S direct into the 1865 or in the 74H chip is necessary.

Been trying to get an answer for quite a while, appreciate the advice.

I once designed, but never made, a 16/44.1 i2s to ad1862 design using this method. Im not sure of your skill in pcb design and soldering because flying wires will be messy and jittery. Better to use smd for this.

I'm not that good with PCBs and jitter is the main concern obviously. Soldering skill are ok but it sound very complex rather than putting the wires into the 74H or direct to the 1865.

I'll check out your project. Thanks for the link!

It will work with shift register 74HC164s.

Just to be clear, this is NOT my design or idea. I just copied it, designed a pcb, first time I designed any pcb btw, and then did nothing with that.

This is what you need:
Black Crow - SGD43.00 : Welcome to the diyparadise e-store!

I've one new, may be I can sell. I must think about.
Or you can contact Jeo, also to verify the compatibility.

You cannot feed I2s directly into the 1865 as it does not support it. (someone suggested this maybe because Analog Devices had not licensed I2S from Philips)

You have to separate the left and right streams by gating the data with the frame sync as AudioNote do so a 74HC02 is needed. You can be sure if it was possible to use I2S AN would have done it.
