Chapter 1: Overview for Cyclone V Device Family  
Enhanced Configuration and Configuration via Protocol  
Cyclone V devices have up to eight PLLs, each with nine output counters that you can  
use to reduce PLL usage in two ways:  
Reduce the number of oscillators that are required on your board by using  
fractional PLLs.  
Reduce the number of clock pins that are used in the device by synthesizing  
multiple clock frequencies from a single reference clock source.  
Cyclone V devices use a fractional PLL architecture in addition to the historical  
integer PLL. If you use the fractional PLL mode, you can use the PLLs for precision  
fractional-N frequency synthesis—removing the need for off-chip reference clock  
sources in your design. The transceiver fractional PLLs that are not used by the  
transceiver I/Os can be used as general purpose fractional PLLs by the FPGA fabric.  
Apart from frequency synthesis, on-chip clock deskew, jitter attenuation, counter  
reconfiguration, programmable output clock duty cycles, PLL cascading, and  
reference clock switchover, the PLLs in the Cyclone V devices also support the  
following key features:  
Programmable bandwidth  
User-mode reconfiguration of PLLs  
Low power mode for each fractional PLL  
Reference clock switchover  
Dynamic phase shift  
Direct, source synchronous, ZDB, external feedback, and LVDS compensation  
Enhanced Configuration and Configuration via Protocol  
Cyclone V devices support 3.3-V programming voltage and several configuration  
modes. Table 1–14 lists the configuration modes and features supported by the  
Cyclone V devices.
