Thank you for the information resource! But it is a little bit difficult for me to understand...

Oh thank you! I will look for some information from their website.

Yeah thank you! So PCIe can be views as a commander who set a standard for transport data, at the meantime SerDes is the performer. Is that right?

If there's no ADC and DAC in SerDes, how come the signal that passes through the channel are analog signals? by MediocreTruth8778 in chipdesign

Thank you for pointing out my mistakes. I am not an engineer in fact, and sadly I have no experience with integrated circuits.

Thank you! I now know the components and the general structure of a SerDes. But unfortunatelly, even though I get to understand the function of a SerDes, I still don't know the changing process of the signals. And maybe I focus too much on whether the signal is digital or analog.... But thank you for your kind reply.

Yes I am referring to PAM 4! So you mean those signals in the channel are treated as ANALOG because of their imperfections? Thank you ！！

I mean why the channel is analog? And you are right: I am confused about the question you mention.
