4.2.3. External Clock Outputs
Each PLL of Intel® Cyclone® 10 LP devices supports one single-ended clock output or one differential clock output. Only the C0 output counter can feed the dedicated external clock outputs without going through the GCLK. Other output counters can feed other I/O pins through the GCLK.
Each pin of a differential output pair is 180° out of phase. The Intel® Quartus® Prime software places the NOT gate in your design into the I/O element to implement 180° phase with respect to the other pin in the pair. The clock output pin pairs support the same I/O standards as standard output pins.
Intel® Cyclone® 10 LP PLLs can drive out to any regular I/O pin through the GCLK. You can also use the external clock output pins as GPIO pins if external PLL clocking is not required.
