Hello,
Basically : I2S is interface, PCM is a digital representation of an audio signal.
"I2S, also known as Inter-IC Sound, Integrated Interchip Sound, or IIS, is an electrical serial bus
interface standard used for connecting digital audio devices together. It is used to communicate PCM
audio data between integrated circuits in an electronic device."
Have a great day,
Yuri

Dear Yuri,
Thanks for your reply.!!..
So there is nothing like PCM interface ?
Can you explain I2S audio format too?
Thanks in advance.
Hi,
Please look at sections 3.1 (General PCM Codec) and 3.2 (I2S) of the following
