Notes to
(1) When J = 3 to 10, use the serializer/deserializer (SERDES) block.
(2) When J = 1 or 2, bypass the SERDES block.
(3) Clock Boost Factor (W) is the ratio between input data rate to the input clock rate.
(4) The maximum ideal frequency is the SERDES factor (J) x the PLL maximum output frequency (f
(5) You must calculate the leftover timing margin in the receiver by performing link timing closure analysis. You must consider the board skew margin,
(6) You can estimate the achievable maximum data rate for non-DPA mode by performing link timing closure analysis. You must consider the board skew
(7) This is achieved by using the LVDS and DPA clock network.
(8) If the receiver with DPA enabled and transmitter are using shared PLLs, the minimum data rate is 150 Mbps.
(9) This only applies to DPA and soft-CDR modes.
(10) This only applies to LVDS source synchronous mode.
