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 utilizing 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. If needed, external logic hardware such as buffers may be used to compensate any timing differences.
