Drive NOS AD1865/62,PCM1704/02/63,TDA1541 from FIFO: Universal I2S-PCM driver board

[qusp]

hmm, well I kinda like solar Jfets myself =) and i'm pretty happy with ESS, but I would have definitely jumped on this GB to play with a new high bandwidth DSD capable multibit chip. unfortunately as a group us audiophiles dont really have that much buying power vs the unwashed, but the day is coming where short-run component Fabs will become a reality even for us. It will be expensive and time consuming, but probably not much more-so than scouring the planet for EOL silicone

but of course I can see your POV there

Since Vzs has already evaluated the daughter board on AD1865 with success, it seems we can confirm now it works well with AD1865. Thanks Vzs for your great job contributed to the community.

Now I’m calling another experienced DIYer for a quick evaluate on PCM1704. In this case, the volunteer should have a PCM1704 DAC to hoop up to. It would be better having FIFO KIT working together because the well done interface and matching connectors, but it’s not a must. I thank you for your contribution to the community in advance. I’ll make another finished and tested daughter board for evaluation for free (I contribute to the community too.)

I already have some PCBs. But I don’t want providing them without fully verification and evaluation.

Another question is what kind of kIT I should provide, KIT with bare PCB or finished and tested board. If I provide KIT with bare PCB, I’m sure many of you will be OK with it, but others may have big problem to solder the SMT parts and to test the board, and I have to provide supports for very basic assemble problem which usually very hard to locate and fix over internet. But If I provide the finished board, I have to go through the SMTA factory that will increase the cost by $10 to $20 on each board according to the quantity. Please let me know your point.

Happy New Year!

I'm offering to evaluate pcm1704.

I think Regal might be the man for this, seen as he is so vocal about 1704 NOS.

I've been waiting for the board to be confirmed as working with 1704 and then I'll add myself to the list of interested.
I have 8x 1704K and intend to build a DAC with them, but I do not already have the FIFO. But if noone else steps up to the plate it is the motivation I need to get it done.

With regard to kit/finished. I'd rather finished and tested for the sake of $20.

I don't have the FIFO, so if other person is more qualified I left my offer to evaluate.

I have USB-I2S: Xmos by Lorien & Combo384 by Amanero.

Yes, another vote for a finished board.

Recently I have re-built my own PCM1704 DAC and want to try NOS! But I do not have FIFO KIT...
I vote for finished board because it is too complicated for me to assemble and test the board.

yeah Regal would seem a good choice to me also, he seems to have been spending too much time in simulators lately for my liking

Yes but unfortunately my time off from work is about to end. Will have to let someone else pioneer this one, about to be on one of those 24/7 projects starting next week, can't wait

Ian, any experience with TDA154x (1541)?
