LVDS SERDES Specifications

Table 63.  D-Series and E-Series Device Group A FPGAs LVDS SERDES Specifications

LVDS serializer/deserializer (SERDES) block supports SERDES factor J = 4 and 8.

DDR registers support SERDES factor J = 1 and 2.

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.

116 Clock Boost Factor (W) is the ratio between the input data rate and the input clock rate.
117 Requires package skew compensation with PCB trace length.
118 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.
119 The VCC and VCCP must be on a combined power layer and a maximum load of 5 pF for chip-to-chip interface.
120 The minimum specification depends on the following factors. The differential I/O buffer within the IOE does not have a minimum data rate.
  • The clock source, such as the PLL and clock pin
  • The clock and data routing resource
121 You must perform design timing analysis in Quartus® Prime to achieve timing closure and run IBIS/HSPICE simulations to ensure that the I/O buffer's electrical performance meets the interface requirements.
122 Not applicable for DIVCLK = 1.
123 This applies to default pre-emphasis and VOD settings only.
124 1.05 V, 1.1 V, and 1.2 V True Differential Signaling I/O standards on receiver supports data rate up to 1000 Mbps.
125 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.
126 Clock Boost Factor (W) is the ratio between the input data rate and the input clock rate.

133 This applies to default pre-emphasis and VOD settings only.
134 When operating in DPA mode, you must enable the receiver equalization feature of the input buffer.
135 1.05 V, 1.1 V, and 1.2 V True Differential Signaling I/O standards on receiver supports data rate up to 1000 Mbps.
