Hi Ti,

on which speed SGMII is working in this device? Is it 1.25G or 125M?

Best regards,

Hello Rafal,

Clock rate is 1.25GHz but obviously data rate is 100Mbps.

Regads,

Ok, understood. Is in TI portfolio any 100M SGMII PHY with clock rate 125MHz?

Hello Rafal,

May be I did not get your question correctly. DP83TC812 should work fine with any MAC supporting 100Mbps operation via Sgmii (as is used very frequently). Do you see any particular requirement from MAC side?

Vikram

Hello Vikram,

I have a MAC which for 100Mbps is using 125MHz refclock for SGMII instead of usually used 1.25GHz,
