SGTL stereo codec replaced by DAC is it possible?

Hi guys,

I received a design here using imx53qsb with a DAC CS4349 instead of the included sgtl5000 stereo codec from FSL.

Can you comment on this design guys?

I don't know how to go about creating a driver on this DAC and integrating it to ALSA/ASoC.

And I don't think porting the sgtl5000's driver is possible bec. they are totally different? well that's just my assumption bec. sgtl5000 is a codec while a DAC is just a converter right?

Any inputs on this would be greatly appreciated.

Thank you and have a nice day.

For playbacking, the sgtl5000  can be replaced by CS4349 which consists of SAI interface, 2 DAC, 2 AMP, Filter, etc. But please keep in mind that sgtl5000 is much powerful than CS4349, SGTL5000 support path config, audio processing, mixing, 5/7 band EQ, for both playback/recording. A lot of SW work should be done if CS4349 to support these features.

Hi Chongbin,

I found that the SGTL5000 is having only 45mW max in output. So, if i want to connect the loud speaker then SGTL5000 is not giving very good sound. Do you have anyother IC recommend to give more watts of audio output.

Thanks & Regards,

RAM
