D1A
In the SAME_EDGE mode, the data is presented into the FPGA fabric on the same clock
edge. However, the data pair to be separated by one clock cycle. This structure is similar to
the Virtex-II, Virtex-II Pro, and Virtex-4 FPGA implementation.

timing diagram, the output pairs Q1 and Q2 are no longer (0) and (1). Instead, the first pair
presented is pair Q1 and Q2 (0) and (don't care) respectively, followed by pair (1) and (2) on
the next clock cycle.
D0A
In the SAME_EDGE_PIPELINED mode, the data is presented into the FPGA fabric on the
same clock edge.
Unlike the SAME_EDGE mode, the data pair is not separated by one clock cycle. However,
an additional clock latency is required to remove the separated effect of the SAME_EDGE
mode.
SAME_EDGE_PIPELINED mode. The output pairs Q1 and Q2 are presented to the FPGA
fabric at the same time.
