3. The RBC clock skew is calculated as t

.
4. The receiver latency, as shown in Figure 5, is defined as the time between receiving the first serial bit of a parallel data word (as
defined as the first edge of the first serial bit) and the clocking out of that parallel word (defined by the rising edge of the receive
byte clock, either RBC1 or RBC0).
