Clock Resource
This chapter describes the hierarchical clock networks and phase-locked loops (PLLs)
which have advanced features in Stratix
ability to reconfigure the PLL counter clock frequency and phase shift in real time,
allowing you to sweep PLL output frequencies and dynamically adjust the output
clock phase shift.
The Quartus
devices. The following sections describe the Stratix IV clock networks and PLLs in
detail:

■
The global clock networks (GCLKs), regional clock networks (RCLKs), and periphery
clock networks (PCLKs) available in Stratix IV devices are organized into hierarchical
clock structures that provide up to 236 unique clock domains (16 GCLKs + 88 RCLKs
+ 132 PCLKs) within the Stratix IV device and allow up to 71 unique GCLK, RCLK,
and PCLK clock sources (16 GCLKs + 22 RCLKs + 33 PCLKs) per device quadrant.
