Notes to
(1) These external clock enable signals are available only when using the ALTCLKCTRL megafunction.
(2) PLL#_CLKOUTp and PLL#_CLKOUTn pins are dual-purpose I/O pins that you can use as one single-ended or
Each pin of a differential output pair is 180° out of phase. The Quartus II 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 (in the top and bottom banks) as well as LVDS,
LVPECL, differential HSTL, and differential SSTL.
To determine which I/O standards are supported by the PLL clock input and output
pins, refer to the
Cyclone III device family PLLs can drive out to any regular I/O pin through the
GCLK. You can also use the external clock output pins as general purpose I/O pins if
external PLL clocking is not required.
