7.4. Continuous Time Linear Equalization
Each supported receiver uses a programmable equalization circuit that boosts the high-frequency gain of the incoming signal to compensate for the low-pass characteristics of the physical medium.
You can set this feature to automatically tune the receiver equalization settings based on the frequency content of the incoming signals. Through the automatic tuning, you can obtain the optimal CTLE settings.
The M-Series FPGAs support a one-time receiver CTLE calibration. If you enable this feature, the calibration finds a stable receiver equalizer setting. Once found, the feature locks the equalizer value to the stable setting.
