Hi Ian

It great and thanks for your effort for the GB. I will order one FIFO kit and one Dual clock board

 

[pedefede]

Hi Ian

will order
- one FIFO kit
- one Dual clock board

peter

 

[regal]

1 x I2S FIFO KIT
4x 4" Cables

thanks

 

[wktk_smile]

Hi,

I 'd like to order one FIFO kit, one dual-clock board.

 

[qusp]

wow Ian, and guys, having one of these sets here, i can say without bias that is a pretty excellent price! the boards are very high quality, better than most of the kits here. just the spdif input board is the best i have seen and that price is better than un-assembled lesser kits elsewhere that are not as complete. the i2s fifo has no competitors that i know of. for full disclosure i havent tested mine out yet, just admired it and it was a generous gift from Ian, so keep that in mind.

snap them up while you can imo

 

[gvelim]

impressive kit.. for me:

1 x I2S FIFO KIT
1 x Dual XO Clock board
1 x S/PDIF Interface Board

I guess that's all I need for stand along setup.

 

[Algar_emi]

I'll buy all three kit (and if possible the free adapter PCB

As for the 50 ohms accessory cables, I'll take two 4'' long cables.

I'm sending you the private email. Thanks alot.

[necplusultra]

Is it possible to purchase an unpopulated kit?

 

[qusp]

having seen the boards, i dont think that is a wise idea to try to solder yourself and good luck getting the parts for that pricing.

@ Algar_emi this 2 cables is just for spdif? 2 cables wont do all that much to help with i2s connection unless you are just using them for mclk and nothing else

 

[pedefede]

Hi Ian

will order
- one FIFO kit
- one Dual clock board
peter

and also:
- one spdif-board
- 6 pieces of 4'' double-ended 50 ohm coaxial cable $2 USD/ea

Peter

 

[randytsuch]

One I2S board, and one dual clock board please

Thanks
Randy

 

[Forane12]

one of each please

 

[neb001]

One of each for me as well please:

1 x I2S FIFO KIT
1 x Dual XO Clock board
1 x S/PDIF Interface Board

Hi necplusultra​

Very good question. I understand what you mean. Just let me explain why I couldn’t just supply the empty PCB and components.​

Different from those discrete 74 logic boards which you could test point to point by yourself, the FIFO board has all the logic state machines running at decades of MHz inside the FPGA/CPLD. Even though you could solder those SMT components with perfect, you still have to face the problems of ISP and testing. For example, the on-board FIFO memory has 4 megabit cells, if some of them have reading or writing glitch occasionally, you might be noticed something wrong by listening, but you can’t address it. ​

Beside the FIFO board, another FPGA based dedicated test board was designed at same time. That test board could takes over all the input and out ports of the FIFO KIT, scan all the functions and cells by performing loop testing to make sure everything is good with bit perfect, as well as the S/PDIF board and the clock board. All of the boards for the group buy have to pass that test before delivery. Otherwise, it would be a big trouble for both of us.

Have a good night! Regards,​

Ian​
