TDA1541 info

I know that pin4 is activated in the TDA1541A, since it is the right channel digital input, when set up in simultaneous mode.
What I wanted to know, is if the pin4 can be used as a SCK input when the DAC is set up in I2S mode.

Thanks

I think so. Pin 2 & 4 could be strapped together while SCK is connected to pin 2.

With TDA1541 pin4 is SCK in I2S mode, clocking the output latch.

With TDA1541A pin4 is nothing in I2S mode, i've connected it to dgnd in my dac and i still here music

Well, to sum up :

I2S -----> TDA 1541A

EF ----> DGND
SCLK ----> PIN 2
WCLK ----> DGND
DATA ----> PIN 3
GROUND ---> DGND
V4 ---> DGND

Pin 27 & 28 ---> +5V

What about PIN 1 ???


Regarding the PIN 4 of the TDA 1541A it's either DGROUND or SCLK as well.

The 1541A datasheet says DGND

ZERS: pin 4 in the non A version is SCK
for the A version in IIS mode, it's not used (officially) and should be connected to ground and not to BCK (pin 2) (it's not the same as SCK)


And I don't know what you was reffering to in your last post, but it seems wrong. IIS has 3 signals (BCK, WCK and DATA), there's no SCK in it. (neither EF or V4)

I'm refering to the CDPRO2 datasheet (a philips drive) that could sent I2S to a DAC chip.

Unfortunatly, the datasheet is too big to be attached

Here is a part of it :

IS2 output :

PIN1 : EF : C2 error flag
PIN2 : SCLK : serial clock
PIN3 : WCLK : world clock
PIN4 : DATA : data
PIN6: GROUND
PIN7: V4 : versatile output

[Bricolo]

Can you post a link to this datasheet? It looks strange


Of course, there was a mistake in my previous post. IIS has DATA BCK and WS

[Bricolo]

OK, I found the datasheet


Pin1 is unused for a DIY dac
Pin2 is BCK
Pin3 is WS
Pin4 is DATA
Pin6 is GND
I don't know what is pin7 used for

[ZERS]

here it is

look at page 13

As said here, the TDA1541(A) can only handle BCK, DATA and WS.
So i think it is:

DATA->DATA
SCLK->BCK
WCLK->WS
GROUND->GROUND

But that is without looking at the datasheet. The other pins are OUTPUTS, so leave them NOT CONNECTED, unless you want to your CDPRO

arg, you guys posted before me.

OK thanks
