e FMAX specification is based on the fast clock used for serial data. e interface FMAX is also dependent on the parallel clock domain which is
design dependent and requires timing analysis.

Arria V GZ RX LVDS will need DPA. For Arria V GZ TX LVDS, the receiver side component must have DPA.
Arria V GZ LVDS serialization and de-serialization factor needs to be x4 and above.
Requires package skew compensation with PCB trace length.
Do not mix single-ended I/O buffer within LVDS I/O bank.
Chip-to-chip communication only with a maximum load of 5 pF.
e minimum specification depends on the clock source (for example, the PLL and clock pin) and the clock routing resource (global, regional, or
local) that you use. e I/O differential buffer and input register do not have a minimum toggle rate.
e maximum ideal data rate is the SERDES factor (J) x the PLL maximum output frequency (fOUT) provided you can close the design timing and
the signal integrity simulation is clean.

You can estimate the achievable maximum data rate for non-DPA mode by performing link timing closure analysis. You must consider the board
skew margin, transmitter delay margin, and receiver sampling margin to determine the maximum data rate supported.
