Default About Audio formats.

Hello,

I need some clarification about Audio data formats.

Is I2S the same of PCM?
I'm planning a project with digital audio using an STA310 processor witch outputs the audio in PCM.
Can I feed this PCM output to the TI TAS5518 processor witch has I2S inputs?

Many Thanks.

I doubt that you can achieve anything without knowing the basics.
PCM is a software FORMAT to represent an analogic signal.
I2S is a hardware link that is used to TRANSPORT the digital signals.

Analogy: you are asking if the music notes are the same thing as the paper that holds them.
