2. Intel® Agilex™ I/O Features and Usage

The I/O buffers in Intel® Agilex™ devices provide the following features:

  • Single-ended non-voltage referenced and voltage referenced I/O standards
  • Differential voltage-referenced I/O standards
  • True differential transmitters and receivers
  • Serializer/deserializer (SERDES)
  • Programmable slew rate
  • Programmable bus-hold
  • Programmable weak pull-up resistor
  • Programmable differential output voltage (VOD) for true differential output buffers
  • Programmable open-drain output
  • On-chip series termination (RS OCT) with and without calibration
  • On-chip parallel termination (RT OCT)
  • On-chip differential termination (RD OCT)
  • Dynamic on-chip parallel termination
  • Internally generated VREF with DDR4 calibration
  • Programmable pre-emphasis for true differential output buffer
  • Programmable de-emphasis for voltage-referenced I/O standards
  • Schmitt trigger input buffer
