The transmitter latency, as shown in Figure 4, is defi ned as the time between the latching in of the parallel data word (as triggered by the rising
edge of the transmit by clock, REFCLK) and the transmission of the fi rst serial bit of that parallel word (defi ned by the rising edge of the fi rst bit
transmitted).
