The timing parameter values specified in this data manual do not include delays by board routes. As a good board design practice, such delays must always be taken into account. Timing values may be adjusted by increasing/decreasing such delays. TI recommends using the available I/O buffer information specification (IBIS) models to analyze the timing characteristics correctly. To properly use IBIS models to attain accurate timing analysis for a given system, see the Using IBIS Models for timing Analysis application report (literature number SPRA839). If needed, external logic hardware such as buffers may be used to compensate any timing differences.
