Cyclone V GX: PLL on LVDS banks & fPLL

Hi Pascal

Thanks for your inquiry.

The Cyclone V device family contains fractional PLLs that can function as fractional PLLs or integer PLLs.
The output counters in Cyclone V devices are dedicated to each fractional PLL that support integer or
fractional frequency synthesis.

We can refer to Table 4 of doc below:

Depends on which member code you are using, there are multiple number of fPLLs can be used.

You can refer to doc below for more Cyclone V PLL information:
