Hi all,

So ... hopefully I'm finally close to testing my new DAC with the Amanero (DSD1794 + combo384) board but am a bit unsure of where to connect the pins ... Hope one of you can help with this ...

(I've attached a copy of the relevant datasheet page for the DSD1794)

As far as I can figure out the connections should be as this (for PCM only):

Amanero pin 3: I2S DATA/DSD1 ---> PDATA on the DSD1794
Amanero pin 4: I2S CLK/DSD CLK ---> PBCK on the DSD1794
Amanero pin 5: I2S FSCLK/DSD2 ---> PLRCK on the DSD1794

MCLK (on the combo384) or SCK on the DSD1794 is not to be used .... ?

Assistance is appreciated :-)

Greetings,

Jesper

peterpopo,

I believe amanero sends a pm for payment as required, so hopefully we get asked soon!

I found an old Pedja Rogic TDA1541 non-oversampling dac board, is it a simple matter to connect an Amanero directly to WS,BCK,DATA,GND or isn't as simple as that?
If it is possible anyone know the corresponding connections on Amanero board.

Yes, TDA1541 works with Amanero out of the box.
Connections are rather direct and intuitive -
WS = LRCLK = FS (Frame Sync)
BCLK = BITCLOCK
DATA = DATA

Don't forget to use a ground wire next to each signal wire - use ribbon with the following arrangement:
GSGSGSGSG
where S means signal and G means ground(GND).


Confirmed up to 96kHz material.
192/174kHz doesn't work as the Amanero hit TDA's limitation on BCLK frequency of 5.6MHz (BCLK=32Fs on TDA Vs BCLK=64Fs on Amanero)
