To perform the simulation with the Keystone SerDes AMI Model, the parameters of the model must be set. Therefore I have some questions.
SGMII:
For the adaptive equalization settings (EQ = 0001b or 1xxxb), I understand that as follows.
- The low frequency gain of the equalizer is determined algorithmically by analyzing the data patterns and transition positions in the received data.
What is the range of the low frequency gain(dB)?
For the fully adaptive equalization setting (EQ = 0001b), I understand that as follows.
- The zero position is determined by the selected operating rate. If the low frequency gain reaches the minimum value, the zero frequency is then reduced. Likewise, if it reaches the maximum value, the zero frequency is then increased.
What is the range of the zero frequency(Hz)?
SRIO:
For the fully adaptive equalization setting (EQ = x01b), I understand that as follows.
- The zero position is determined by the selected operating rate and the low frequency gain of the equalizer is determined algorithmically by analyzing the data patterns and transition positions in the received data.
If the pre or post cursor equalization analysis (EQ = x1xb) is performed, the data patterns and transition positions in the received data are analyzed to determine whether the transmit link partner is applying more or less pre or post cursor equalization than necessary.
What is the range of the low frequency gain(dB)?
What is the range of the zero frequency(Hz)?
