5. I/O Features in Cyclone® V Devices

This chapter provides details about the features of the Cyclone® V I/O elements (IOEs) and how the IOEs work in compliance with current and emerging I/O standards and requirements.

The Cyclone® V I/Os support the following features:

  • Single-ended, non-voltage-referenced, and voltage-referenced I/O standards
  • Low-voltage differential signaling (LVDS), RSDS, mini-LVDS, HSTL, HSUL, and SSTL I/O standards
  • Serializer/deserializer (SERDES)
  • Programmable output current strength
  • Programmable slew rate
  • Programmable bus-hold
  • Programmable pull-up resistor
  • Programmable pre-emphasis
  • Programmable I/O delay
  • Programmable voltage output differential (VOD)
  • 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)
  • High-speed differential I/O support
Note: The information in this chapter is applicable to all Cyclone® V variants, unless noted otherwise.
