The external memory interface clock output jitter specifications use a different measurement method, which is available in the "Memory Output
Clock Jitter Specification for Arria V GZ Devices" table.

This specification only covered fractional PLL for low bandwidth. The fVCO for fractional value range 0.05–0.95 must be ≥ 1000 MHz.
The cascaded PLL specification is only applicable with the following condition:
a. Upstream PLL: 0.59Mhz ≤ Upstream PLL BW < 1 MHz
b. Downstream PLL: Downstream PLL BW > 2 MHz
