Wouldn't think so. It's a fully digital interconnection net.

Depends on the media type. Popular 10GBASE-T is using an "analog" 16PAM modulation over the 4 pairs of a Cat 6 cable.
Of course it's using ADCs on the receiver side. See IEEE 802.3-2008_section4, clause 55 for the specification of the standard
and manufacturer information, e.g. from Broadcom for the implementation details.
 

Ok, didn't know that. Thank you!
 

typically the ADC will be 8-9bits running at 125Meg.
