Default Repetita iuvant.... or not?

As said before there is no need of glue logic.
Do a search on the thread where spencer sells his DIR9001->CS8412 adapter, it's all there.

Probably you only have to set I2S mode, even if it's at 24 bit.
The TDA will just ignore the lower bits.

Hello


Andypairo and Leo

Andypairo said "TDA will just ignore the lower bits..."

Leo said "It means 4 bits will be lost (the last 4 LSB). "

But the last significant bit are important, it would lost important low level and soundstage informations ?

Looking at a schematic of spencer DIR9001->CS8412 adapter, it seem that we still need to use the CS8412.


Anbello

I will look at this chinese bbs.



Thank to all

Bye

Gaetan

Hi,
since the TDA is a 16 bit converter it just ignores the bits from 17 to 24.
But, if the source is a 16 bit CD, those bits are all zeroes!

Here's the schematic for the DIR9001/TDA1543 DAC that anbello referred to: http://www.pic16.com/soft/TDA1543SCH.pdf

To use the TDA1541A instead of the 1543, the connections to pins 1 and 2 have to be interchanged and connection to pin 3 remains the same. It works - I've had it playing.

The CS8412 isn't a physical device on the adapter. The CS8412 schematic symbol is only used get the correct pin sequence and footprint for the adapter to work as a plug in replacement for a CS8412....

Hello John

What is the K1 - K3 switch in that schematic ?

Thank

Hello Gaetan -

It's just for switching between the two inputs.

24 bit is the max that DIR9001 can handle. If input is 16 bits (which is still current audio standards) the DIR9001 will output 16 bit I2s.

My TDA1541A DAC used a DIR9001 receiver (use Spencer Kit)

Hello

Using only coax SPDIF input, do I need to keep the 74HC00 in that circuit, could I connect the coax SPDIF input directly to RXIN of the DIR9001 ?

Btw, I may add a SAA7220 with a reclock.

Thank

Bye

Gaetan
