1.2.4. Differential I/O Pins

Note: Altera recommends that you create an Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software will check your pin connections according to I/O assignment and placement rules. The rules differ from one device to another based on device density, package, I/O assignments, voltage assignments, and other factors that are not fully described in this document or the device user guides.

I/O, RX/TX channel

These are LVDS SERDES channels on HSIO banks. If these pins are not used in LVDS SERDES implementation, these pins are available as user I/O pins.

Supported I/O standards:

  • 1.3-V I/O standard for true differential I/O
  • 1.3-V I/O standard for single-ended non-voltage referenced I/O
  • 1.2-V I/O standard for single-ended voltage referenced and non-voltage referenced I/O
  • 1.2-V I/O standard for differential voltage referenced I/O
  • 1.2-V I/O standard for true differential I/O
  • 1.1-V I/O standard for single-ended voltage referenced and non-voltage referenced I/O
  • 1.1-V I/O standard for differential voltage referenced I/O
  • 1.1-V I/O standard for true differential I/O
  • 1.05-V I/O standard for single-ended voltage referenced and non-voltage referenced I/O
  • 1.05-V I/O standard for differential voltage referenced input
  • 1.05-V I/O standard for true differential I/O
  • 1.0-V I/O standard for non-voltage referenced I/O

These pins support the programmable pull-up resistor. For more information, refer to the Agilex™ 5 FPGAs and SoCs Device Data Sheet .

For more information about the I/O placement guidelines, refer to the General-Purpose I/O User Guide: Agilex™ 5 FPGAs and SoCs .

Connect unused pins as defined in the Quartus® Prime software.
