hi there!
As I want to try my TDA1541 with oversampling I was searching for a digital filter thats more ore less easy available.... no result....
So I thought what would be if I feed the TDA with a AD1892 Sample rate converter at 96kHz... that must be, as i have understand it, some sort of 2,..x oversampling???
Or do I misunderstud something.....
The meaning is not to get better sound, only for the thing itself...

SM5843AP digital filter from NPC is available. It can output I2S but needs Japanese formats at the input. No problem when you use a CS8412.

This would appear to contradict the datasheet, in which there is no reference to a I2S output.

You're right Ray.
Typo and edit: it should have been SM5840. It was late when I posted yesterday and it happens that I have em both in stock 😉 But it can only input I2S, outputs are in the other formats which makes it useless for connecting to TDA1541A. I have a Philips cdplayer with this digital filter in it in combination with a Philips DAC, that's why I mentioned it. But I just checked and it has extra logic for connecting to the DAC chip. It contradicts with earlier posts as well:

I am sure SAA7220 will work

Hey Jocko, would you send them to me like TI sends the samples to me ;-) no costs, shipped in one week to austria, hehe....
No, real, do you think it´s worth to try it? I mean I´m very satisfied with my non-os TDA´s.....

Hi Jocko, do you know of a DIL digital filter that accepts I2S at in and outputs ? I gave up years ago to find a replacement for SAA7220 but this thread inspired me to do some research again. Did not find a single one.
The TDA1373 numbers I2S i/o and digital filtering amongst its many features but though it has been recently EOL'ed it may still be available.
The other option is to use glue logic to adapt any currently available filter.

Hello Weissi, are you sure SM5841A can do that without glue logic ?
BTW I plowed through the datasheet of TDA1373 and I don't think it is the chip for this task. It's a DIR/SRC/digital filter.
Read something about bitstream outputs so I am not very sure if it would work. It can be me but those Philips datasheets are hard to read and practical implementation isn't highlighted.

When was it available to DIYers? I think you had to buy a license from Microsoft (who bought HDCD from Pacific Microsonics) to design it in last time I heard......

Incidently, I was there when they made the first HDCD recording of the Dallas Wind Symphony. I thinck that might have been the first commercial recording made with the process.

Oh...
Ok, Fred.
I didn't know that...
Anyway, I have one on my Audio Alchemy.
It's on a socket.
I sell it for a good price.😀
Just joking...😎
Or not.
