Timing Characteristics of 2:1 SDR Serialization
Table 8-11: OSERDES Switching Characteristics (Continued)

X-Ref Target - Figure 8-17
Clock Event 1
On the rising edge of CLKDIV, the word AB is driven from the FPGA logic to the D1 and
D2 inputs of the OSERDES (after some propagation delay).
Clock Event 2
On the rising edge of CLKDIV, the word AB is sampled into the OSERDES from the D1 and
D2 inputs.
Clock Event 3
The data bit A appears at OQ one CLK cycle after AB is sampled into the OSERDES. This
latency is consistent with the
CLK cycle.
