I have seen a simple design using this chip in a few places on the forum and it looks interesting. I do have a question if anyone can help. I understand it needs i2s input. If i have an old cd player with 11.2mhz clock and 7310/7220 chipset, can i use this as the i2s source or is it at the wrong clock frequency?

Hi Rotellian,
Yes you can use the SAA 7310 as a source for the I2S signals if you want to construct a NON-OS DAC.
See Marco's site:

You need pin 2, 3 & 4 on the SMD package. Hope this helps.

Excellent - thought so. That dac is ridiculously cheap - even in the uk! Be something fun to do 🙂 Cheers
Konnichiwa,
If your player has the 7310 & 7220 it is almost invariably bound to have also a TDA1541. The TDA1541 is a much superior performance and soundquality chip to the 1543. So I would not recommend to "downgrade" the Player....

Its a 7323 philips bitstream actually (nice midrange - terrible bass). But i do have another one with 7210/7220 that is in need of a new cdm4/19 (which i might just have found in another old player - not that I collect old cd players you understand!) that does have 1541 (have converted to non-oversampling upgraded op-amps and few bits - is quite nice, but still not right) The quest continues.....
MY tda1543 non-os dac has invariably hum at its output, even with a copper foil as ground plane😕
I guess that although quite simple to build, ground IS a problem to beware of.

If it's a B226 it has CDM1 and TDA1541A. Never owned one so I am not too sure. Electronically not very special and overpriced AFAIK.
I remember that some mechanical part failed more than normal but I can't recall which part 😉
