Default Which oversampling digital filters chips do work with the CS8414 and TDA1541A ?

Hi

Which oversampling digital filters chips do work with the CS8414 and TDA1541A without glue logic ?

I only know the SAA7220, but it's not the best one.

Thanx

Paul

Not a whole lot. I THINK the TDA1541 can be set up to accept Offet Complementary Binary, something which IIRC the Pacific Microsonic PDM100 can output and the 8414 can output pretty much any dataformat under the sun.

Do you have any particular reason for wanting an oversampling filter?

CXD1088 4Fs.
CXD1144 4Fs.
CXD1144 8Fs - Needs 2 dacs.
CXD1244 4Fs.
CXD1244 8Fs - Needs 2 dacs.

The devices below overclock the TDA1541 by running BCK at 256Fs but it seems to work. More here and here
DF1700/SM5813.
PMD100.

PMD100 is possible indeed, but requires some glue logic to create LE and more.

Hi

NOS dac, using a 20k bessel low pass filter, do have some lack of details with orchestral music, it was compared to an old Macintosh cd player, inside this Mac it's a TDA1541A OS dac.

Thanx

Paul

Hi

Looking at the data sheet, the CXD1244 do work at a 48 bit frame and the CS8414 only at a 64 bit frame.

Thanx

Paul

Hi

PMD100 is hard to find.

Thanx

Hi

I have some DIR9001 receiver chips, maby it's a better one to use ?

That chip as a lower jitter compared to the CS8414.

Thanx

Paul
