The timing characteristics of any signal path can be derived from the
timing model and parameters of a particular device. External timing
parameters, which represent pin-to-pin timing delays, can be calculated
as the sum of internal parameters. Figure 12 shows the timing relationship
between internal and external delay parameters.
See Application Note 94 (Understanding MAX 7000 Timing) for more
information.
