DP83TG720S-Q1: SGMII auto-negotiation

Part Number: DP83TG720S-Q1

Hi all,

I get back to you cause I have an other question about the DP83TG720.

Indeed, I would like to have more information about 1000 Base-T1 auto-negotiation and how it works.

It is unclear for me should the auto-negotiation implemented is about to set a master/slave synchronisation (regardless of the chip bootstrapping) with a link partner or it is the same way than a classic PHY 1000 base-T (negotiating at 1000M or 100M and full or half duplex communication).

With a static configuration between a Master and a slave (both set with bootstrap), both at 1000M and full duplex, It is working perfectly but when I turn on an auto-negotiation, nothing happens. 

Thank you for your support,

Best Regards,

Arnaud
