Table 40.  High-Speed I/O Specifications for Arria® V Devices

When J = 3 to 10, use the serializer/deserializer (SERDES) block. When J = 1 or 2, bypass the SERDES block.

For LVDS applications, you must use the PLLs in integer PLL mode.

The Arria® V devices support the following output standards using true LVDS output buffer types on all I/O banks.

  • True RSDS output standard with data rates of up to 360 Mbps
  • True mini-LVDS output standard with data rates of up to 400 Mbps

73 Clock boost factor (W) is the ratio between the input data rate and the input clock rate.
74 This applies to DPA and soft-CDR modes only.
75 This applies to non-DPA mode only.
76 This is achieved by using the LVDS clock network.
77 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.
78 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.
79 The VCC and VCCP must be on a separate power layer and a maximum load of 5 pF for chip-to-chip interface.
80 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.
81 You must calculate the leftover timing margin in the receiver by performing link timing closure analysis. You must consider the board skew margin, transmitter channel-to-channel skew, and receiver sampling margin to determine the leftover timing margin.
82 When using True LVDS RX channels for emulated LVDS TX channel, only serialization factors 1 and 2 are supported.
83 This applies to default pre-emphasis and VOD settings only.
84 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.
