1.1.1. Clock and PLL Pins

Note: Altera recommends that you create a Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software checks 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, Clock Input

Dedicated high speed clock input pins that can be used for data inputs or outputs. Differential input OCT Rd, single-ended input OCT Rt, and single-ended output OCT Rs are supported on these pins.

When you do not use these pins as dedicated clock pins, you can use them as regular I/O pins.

Tie the unused pins to GND or leave them unconnected. If the pins are not connected, use the Quartus® Prime software programmable options to internally bias these pins. These pins can be reserved as inputs tristate with weak internal pull-up resistor enabled, or as outputs driving GND.

I/O, Clock

Dual-purpose I/O pins that can be used as single-ended inputs, single-ended outputs, or external feedback input pins.

For more information about the supported pins, refer to the device pin-out file.

Tie the unused pins to GND or leave them unconnected. If the pins are not connected, use the Quartus® Prime software programmable options to internally bias these pins. These pins can be reserved as inputs tristate with weak internal pull-up resistor enabled, or as outputs driving GND.

I/O, Clock

Dual-purpose I/O pins that can be used as differential I/Os, or external feedback input pins.

For more information about the supported pins, refer to the device pin-out file.

Tie the unused pins to GND or leave them unconnected. If the pins are not connected, use the Quartus® Prime software programmable options to internally bias these pins.

I/O, Clock

I/O pins that can be used as two single-ended clock output pins or one differential clock output pair.

For more information about the supported pins, refer to the device pin-out file.

Tie the unused pins to GND or leave them unconnected. If the pins are not connected, use the Quartus® Prime software programmable options to internally bias these pins. These pins can be reserved as inputs tristate with weak internal pull-up resistor enabled, or as outputs driving GND.
