(1) tAJ increases because of additional attenuation on internal clock path.
(2) When LDEMUX = 1 the output buses are aligned in time requiring the earlier sample(s) to be delayed before outputting on the LVDS buses to align with the later samples. The latency for the buses will be slightly different due to added delays. The number shown is for the worst case bus.
(3) When LDEMUX = 0 the output buses are staggered in time and therefore the start of data frames occur at staggered times. The number shown is for the earliest output frame. The strobe signals are output at the end of a frame so the start of a data frame corresponds to the data output immediately after a strobe output.
(4) Both tAD and tOD increase by the delay introduced by TAD_COARSE, TAD_FINE and TAD_INV when tAD Adjust is used to delay the sampling instant. The total latency through the device does not include the aperture delay. Total latency through device is tLAT = tLAT(DIG) + tOD - tAD.
