Any of the output counters (C[9..0] on the top and bottom PLLs and C[6..0] on the
left and right PLLs) or the M counter can feed the dedicated external clock outputs, as
shown in
all output pins available from a given PLL.
Each left and right PLL supports two clock I/O pins, configured as either two
single-ended I/Os or one differential I/O pair. When using both pins as single-ended
I/Os, one of them can be the clock output while the other pin is the external feedback
input (FB) pin. Therefore, for single-ended I/O standards, the left and right PLLs only
support external feedback mode.
Each pin of a single-ended output pair can either be in-phase or 180° out-of-phase.
The Quartus II software places the NOT gate in the design into the IOE to implement
the 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 High-Speed Transceiver Logic (HSTL),
and differential SSTL.
To determine which I/O standards are supported by the PLL clock input and output
pins, refer to the
Stratix IV PLLs can also drive out to any regular I/O pin through the GCLK or RCLK
network. You can also use the external clock output pins as user I/O pins if you do
not need external PLL clocking.
