Figure 5–10. Cyclone IV E PLL Block Diagram
Notes to
(1) Each clock source can come from any of the four clock pins located on the same side of the device as the PLL.
(2) This is the VCO post-scale counter K.
(3) This input port is fed by a pin-driven dedicated GCLK, or through a clock control block if the clock control block is fed by an output from another

Cyclone IV E devices.
The VCO post-scale counter K is used to divide the supported VCO range by two. The
VCO frequency reported by the Quartus II software in the PLL summary section of
the compilation report takes into consideration the VCO post-scale counter value.
Therefore, if the VCO post-scale counter has a value of 2, the frequency reported is
lower than the f
