Default I2S to PCM convertor board released today

The finial released version is V2.0 now. Half speed mode already included. With this new mode, many old NOS DACs can run up to 384KHz. PCB hardware was designed a couple of month ago, so I could only use IO5 and IO6 as half-speed jumper.

Potato GHz TTL flop-flips were used for re-clocking to get lower phase noise. As well as low noise on-board LDO. Optional external regulator is also possible with connector. Please find the name of pictures below for many other details.

I have to write user’s manual the next. Very small daughter board, but has a lot of functions.

Ian

Ian it looks beautiful! I'm sure there are many itching to get their hands on these

I'm about to go out of town for a week, in the wiki I have added a link to the post above presenting the final hardware revision. When I get back I'll try to do a rundown linking each of the testing pages where you present the logic analyser results if you think that'll be helpful. I don't envy you compiling all of this info into the user manual, that'll be a huge task indeed to cover all of the options that you've made possible with very flexible design.

Cheers,
Chris

I'll send diyAudio message to you once I'm ready. I'll reserve a board for you if you are on the interesting list,

Have a nice weekend.
