2.2.3.1.3. Receiver High-Speed I/O Specifications

Table 119.  Receiver High-Speed I/O Specifications for Arria V GZ Devices

When J = 3 to 10, use the serializer/deserializer (SERDES) block.

When J = 1 or 2, bypass the SERDES block.

196 The FMAX specification is based on the fast clock used for serial data. The interface FMAX is also dependent on the parallel clock domain which is design dependent and requires timing analysis.
197 Arria V GZ RX LVDS will need DPA. For Arria V GZ TX LVDS, the receiver side component must have DPA.
198 Arria V GZ LVDS serialization and de-serialization factor needs to be x4 and above.
199 Requires package skew compensation with PCB trace length.
200 Do not mix single-ended I/O buffer within LVDS I/O bank.
201 Chip-to-chip communication only with a maximum load of 5 pF.
202 The 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. The I/O differential buffer and input register do not have a minimum toggle rate.
203 The 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.
204 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.
