TRUTH TABLES
Table 2 defines the approximate relative delay between the two paths. For example, if S2, S1, S0 = 000, and an edge appears at CLK_IN at the
same instant as an edge appears at DATA_IN, then an edge at CLK_OUT will appear about 350ps earlier than an edge at DATA_OUT. That is,
negative values imply CLK_OUT being shifted early with respect to DATA_OUT. Likewise, a positive value in the third column implies that
CLK_OUT is shifted late with respect to DATA_OUT. Please consult the “AC ELECTRICAL CHARACTERISTICS” section for more precise delay
values.
