Clock and PLL Pins

Note: Intel® recommends that you create an Intel® Quartus® Prime design, enter your device I/O assignments, and compile the design. The Intel® 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 handbook.
Table 1.  Clock and PLL Pins
Pin Name Pin Functions Pin Description Connection Guidelines
CLK_[2,3][A,B,J,K,L]_[0,1]p 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.

Tie the unused pins to GND or leave them unconnected.

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

CLK_[2,3][A,B,J,K,L]_[0,1]n 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.

Tie the unused pins to GND or leave them unconnected.

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

PLL_[2,3][A,B,J,K,L]_FB[0,1] I/O, Clock Dual-purpose I/O pins that can be used as single-ended inputs, single-ended outputs, or external feedback input pin. For more information about the supported pins, refer to the device pinout file.

Tie the unused pins to GND or leave them unconnected.

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

PLL_[2,3][A,B,J,K,L]_CLKOUT[0:1] , PLL_[2,3][A,B,J,K,L]_CLKOUT[0:1]p 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 pinout file.

Tie the unused pins to GND or leave them unconnected.

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

PLL_[2,3][A,B,J,K,L]_CLKOUT[0:1]n 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 pinout file.

Tie the unused pins to GND or leave them unconnected.

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