Hi Gurus,
 

Have a very generic question about Physical Layer Device.

In the PCS i.e the Physical coding sublayer of  the PHY Device why is the
8b/10b encoding/decoding required.

Why not the serial signals received by the MDI directly interfaced with the
MAC without encoding/decoding??

 

Apologies, if this is not related to Signal Integrity...

 

Thanks and Regards,

Ravi..
