Yes if you are building a player in one box (rpi+fifo+dac) you can use the fifo board alone.
you dont need the mclk input for fifo either.
That's a good suggestion, but was mostly aimed at one builder who had a penchant for making things burn rather than doing thorough testing before applying power. Especially note that batteries are capable of higher short circuit current output than many linear power supplies so when powering a newly assembled board for first time .... batteries are a poor choice.
I remembered there was someone in this thread talking about the length of cable and mclk delay.
Here is a real world question:
I'd like to run buffalo III in synchronized mode.
Due to the layout I can choose:
1 3×10cm ufl cable for data and 20cm for clock
2 4×20cm cable for all of them.
Which will work better?

yeah I found that thread qusp said they should be the same length.
ufl cables are so expensive....
Definitely all the same length but I couldn't get a decent lock with 20cm on my dual mono set up. I ended up with these which work perfectly:
U.FL-2LP-088K1T-A-(100) - HRS (HIROSE) - CABLE, PLUG/PLUG, 1.37MM, 100MM | Farnell UK
Yes, not cheap and v fiddly. The longer you get try to increase the diameter of the cable too - I'm trying to find a supplier of 1.78mm cables as Ian recommended them in his FIFO thread.
Hope this helps.

If I tweak my layout a little bit, I can probably try 4*15cm cables.
But what I have right now are either 10cm or 20cm.
The best I can find is 1.32mm from mouser.
The 1.78mm one should be following RG178 standard, which I didnt find any u.fl to u.fl.
Yes, I normally use Mouser but they didn't have what I wanted so I had to go to Farnell...have you tried digikey? Might be worth asking Ian where he sourced the 1.78mm
...Ian?
...Ian?
I found here SMA, 3G UMST EV-DO antenna items in connector store on eBay! , custom cable on request,I waiting for a command from a UFL to UFL RG 178 of 8cm for the MCLK,cost with transport 3,50 Dollard.By against the delivery time is long 25 at 30 days.
you think too much🙂same length for all signals to single output and dual mono,dual mono is specified by Ian because more sensitive to different length.

What I mean same length of u.fl coaxial cable was just for MCLK cables. For other signals, you don't have to use cables with same length, but it would be better longer than the MCLK cable. 🙂

I ordered 178 u.fl cables from our cable supplier, but the minimal order has to be 500 🙂. I couldn't find any 178 cable with u.fl connector from Digikey or Mouse at that time.
178 has less loss. Is there anybody get it compared with normal u.fl cable?
