High-Speed I/O Specifications

Table 47.  High-Speed I/O Specifications for Intel® Arria® 10 Devices

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

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

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.

The Intel® Arria® 10 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

72 –E1S and –E2S speed grades are applicable to both VCC = 0.9 V and 0.95 V. –E3S speed grade is only applicable to VCC = 0.9 V.
73 Clock Boost Factor (W) is the ratio between the input data rate and the input clock rate.
74 This is achieved by using the PHY clock network.
75 Requires package skew compensation with PCB trace length.
76 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.
77 The VCC and VCCP must be on a combined power layer and a maximum load of 5 pF for chip-to-chip interface.
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 serializer do not have a minimum toggle rate.
79 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 meets the interface requirements.
80 Not applicable for DIVCLK = 1.
81 This applies to default pre-emphasis and VOD settings only.
82 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.
