81-GRM21R71H102MA01D

Dear Pavel,
the following article from the BOM is no longer available from Mouser:
81-GRM21R71H102MA01D
Can you update the BOM and could you come up with an alternative.
Thank you

Pavel,

Would you be open to sharing the KiCad project / design files in addition to the schematic and Gerbers? I am interested in making some changes to the board to support some additional features from the Beaglebone.

Thanks!
Greg

How about 74ahc595?
Some available

https://www.ebay.com/itm/15pcs-new-74AHC595D/142818321022?hash=item2140a2a27e:g:acoAAOSw6VNbEiq4

I have tried all the available AHCT595 TI, Phillips, NXP, Nexperia, Diodes.
The fact that Nexperia is different from the NXP discovered quite recently.
The new Nexperia has lower consumption than NXP. SNR worse by 3-5db.
I believe that you do not need to re-install already installed Nexperia. By ear, you will not notice this difference.

Find Phillips or NXP is difficult now. Remains of NXP still exist in some warehouses. But to search you need to make an effort.
I had a stable supplier Phillips, but I cleared his entire warehouse.🙂
Try searching on TaoBao. In the warehouses of China NXP you will find. Do not worry about fakes. These ICs are not profitable to
counterfeit.

Pavel,

Do you happen to have the drawing of the output jacks?

Pavel,


Can you post a picture of an old stock NXP chip? I might have a line on some but I want to verify it's not a Nexperia.

Hi,
what is the actual version of the Amanero software to play DSD 512.
Thank you

 

[thuanth43]

Thanks to Pavel’s gerber, I’ve got some blank boards made according to his suggestion. Some spare sets left, if anyone interested. 🙂 If there’s enough interest, I could provide the Philips AHCT595.
