PLLs & Clock Networks

Stratix Device Handbook, Volume 1
bandwidth is tuned by varying the charge pump current, loop filter
resistor value, high frequency capacitor value, and m counter value. You
can manually adjust these values if desired. Bandwidth is programmable
from 200 kHz to 1.5 MHz.
External Clock Outputs
Enhanced PLLs 5 and 6 each support up to eight single-ended clock
outputs (or four differential pairs). Differential SSTL and HSTL outputs
are implemented using 2 single-ended output buffers which are
programmed to have opposite polarity. In Quartus II software, simply
assign the appropriate differential I/O standard and the software will
implement the inversion. See
