Hi Team,
My customers have some questions about 720.
1. Whether 720 could support getting 1000 base-T1 SQI threshold value？ This "1000 base-T1 SQI threshold value" is different from 《P20_0183_DP83TG720_1G_Test_Report_00D_01》,right?
2. whether 720 have register to record the link lost number (abnormal link down number). We can't find such a register in 720 datasheet.
3. According to <snla371a--Configuring for Open Alliance Specification Compliance.pdf>, the SQI index is obtained through the following register: Mean Square Error 0x875[9:0], what does this MSE specifically refer to? Is the noise RMS value which PHY detected the chain? or the signal-to-noise ratio? Is there a correspondence table between this MSE and the bit error rate BER? Thank you.
