PLLs & Clock
Networks
Altera Corporation
July 2005
clock signals are routed from LAB row clocks and are generated from
specific LAB rows at the DSP block interface. The LAB row source for
control signals, data inputs, and outputs is shown in
Stratix devices provide a hierarchical clock structure and multiple PLLs
with advanced features. The large number of clocking resources in
combination with the clock synthesis precision provided by enhanced
and fast PLLs provides a complete clock management solution.
Global & Hierarchical Clocking
Stratix devices provide 16 dedicated global clock networks, 16 regional
clock networks (four per device quadrant), and 8 dedicated fast regional
clock networks (for EP1S10, EP1S20, and EP1S25 devices), and
16 dedicated fast regional clock networks (for EP1S30 EP1S40, and
EP1S60, and EP1S80 devices). These clocks are organized into a
hierarchical clock structure that allows for up to 22 clocks per device
region with low skew and delay. This hierarchical clocking scheme
provides up to 48 unique clock domains within Stratix devices.
