The receiver input buffer receives serial data from the rx_serial_data port and feeds the serial data to the CDR and deserializer.

Figure 9. Receiver Input BufferStratix V GT channels do not support AEQ and DFE.

The receiver buffer supports the following features:

  • Programmable Equalizer Bandwidth
  • Programmable differential On-Chip Termination (OCT)
  • Programmable VCM
  • AC and DC coupling
  • Signal Threshold Detection Circuitry
  • Continuous Time Linear Equalization (CTLE)
  • DC Gain
  • Decision Feedback Equalization (DFE)
  • EyeQ

You can program these features using the assignment editor and a reconfiguration controller.
