VCO frequency reported by the Quartus II software is divided by the post-scale counter
through a clock control block provided the clock control block is fed by an output from another PLL or a pin driven dedicated global or regional
clock. An internally generated global signal or general purpose I/O pin cannot drive the PLL.

The loop filter converts these up and down signals to a voltage that is used to bias the
VCO. The loop filter also removes glitches from the charge pump and prevents
voltage overshoot, which filters the jitter on the VCO. The voltage from the loop filter
determines how fast the VCO operates. A divide counter (m) is inserted in the
feedback loop to increase the VCO frequency above the input reference frequency.

The VCO output from Left/Right PLLs can feed seven post-scale counters (C[0..6]),
while the corresponding VCO output from Top/Bottom PLLs can feed ten post-scale
counters (C[0..9]). These post-scale counters allow a number of harmonically
related frequencies to be produced by the PLL.
