Arria II GX devices support PLL cascading. If you are cascading PLLs, you must use
PLLs adjacent to each other (for example, PLL5 and PLL6) so that the dedicated path
between the two PLLs is used instead of using a global clock (GCLK) or regional clock
(RCLK) network that might be subjected to core noise. The TimeQuest Timing
Analyzer takes PLL cascading into consideration for timing analysis.
Table 7–4. DLL Reference Clock Input
If you are using the ALTMEMPHY megafunction or UniPHY IP core, Altera
recommends using the dedicated PLL input pin for the PLL reference clock.
Figure 7–12
reference clock goes into the DLL to a chain of up to 16 delay elements. The phase
comparator compares the signal coming out of the end of the delay chain block to the
input reference clock. The phase comparator then issues the upndn signal to the
Gray-coded counter. This signal increments or decrements a 6-bit delay setting
(DQS delay settings) that increases or decreases the delay through the delay element
chain to bring the input reference clock and the signals coming out of the delay
element chain in phase.
