Hi,
I have a problem with my Fifo that I hope you might help me with.

After connecting my Fifo to my M2Tech Hiface evo (I2S output), my BII at the outlet of the dual clock and powered the Fifo with 5VDC. Everything looks ok but it doesn't play music, just silence.

My connection with Hiface evo.
M2Tech Hiface evo out: → Fifo in:
2,4,6,8) Ground → GND
1) SDATA → SD
3) LRCK (FS) → WS
5) SCLK (BIT CLOCK) → SCK
7) MCLK (Not connected)

My connection to BII.
Dual clock out → BII in:
Gnd → GND
SD → D2
WS → D1
SCK → DCK
MCLK (Not connected) since I uses the BII clock.

The fifo LED’s work perfectly and they seems stable. But no music comes out.
When connected and music played the Fifo led indicate locked signal. If I disconnect input signals and the led give the correct respons (the led goes black). The strange thing is that the led for Fifo buffer empty lights up (stable) even when music is played.

On the BII the led indicates that a signal has been locked and everything looks ok.

On the clockboard led for 512 and 44,1 kHz is shining.

You will find a manual on how to use I2S for M2Tech Hiface evo here: http://user.tninet.se/~pst442t/hiface_evo_i2s.pdf
The manual for Buffalo II here: http://user.tninet.se/~pst442t/Buffalo_II_User_Manual_v1.0.pdf


Thankful for all your help!

For info: The BII playes perfectly if the signal goes directly from Hiface to BII.

Santa, albeit late, opted to drive by with (60). Nice stuff!

Thanks Ian!

And it even plays music after hitting the input selector on the s/pdif board - now, a good clock.... it doesn't sound bad at all with the generic osc. but I have a hunch whats going to happen with a really good one 🙂

Sounds great! I'm looking for your good news.

@Ian :
I just received my FIFO (GBIII57), they look great.

I see on SPDIF board have a I2S input via URL. Why I can not use it for connect from I2S Amanero ?.
Click to expand...

u.fl you mean 😀 the u.fl input on the spdif board is for the spdif OUT capability
besides why would you do that? amanero doesnt have u.fl output, the outputs are on wire header/molex type connections. the fifo already has an input connector that would be suitable directly, or via the i2s backdoor connection.

controlled impedance connections are not such a big deal for the inputs to the fifo, its all buffered and spat out again on u.fl anyway. perhaps if you wanted to input the very high rate 352.4/384khz you might look at u.fl but in that case it would perhaps be better to connect to the fifo main board directly.

I have used amanero connected to fifo directly with the molex type connection, at 384khz no problem, so really I think you are making too much work for yourself for nothing given the amanero outputs are not terminated, or impedance controlled connections.
