Max signal routing length includes escape routing.
Multi-board DMD routing lengths shown are the combination that was analyzed by TI.
Due to board variations, create a SPICE simulation for all board designs with the Controller IBIS models to ensure signal routing lengths do not exceed signal requirements.

These routing requirements are specific to the PCB routing. Internal package routing mismatches in the DLPC7540 and DLP471TE, DLP471NE, DLP650TE or DLP651NE have already been accounted for in these requirements.
Training is applied to DMD HS data lines, so defined matching requirements are slightly relaxed.
This requirement must be maintained from the Controller to the DMD, even if the signals traverse multiple boards.
This is an inter-pair specification (that is, differential pair to differential pair within the group).
This is an intra-pair specification (that is, length mismatch between P and N for the same pair). This is applicable to both clock and data.
This is a channel to channel skew specification.
The low speed read control interface from the DMD is single ended, and makes use of the differential write clock. As such, a routing mismatch between these is not applicable.
