(1) Maximum signal routing length includes escape routing.
(2) Multi-board DMD routing length is more restricted due to the impact of the connector.
(3) Due to PCB variations, these recommendations cannot be defined. Any board design should SPICE simulate with the controller IBIS model (found under the Tools & Software tab of the controller web page) to ensure routing lengths do not violate signal requirements.

(1) The length matching values apply to PCB routing lengths only. Internal package routing mismatch associated with the DLPC34xx controller or the DMD require no additional consideration.
(2) Training is applied to DMD HS data lines. This is why the defined matching requirements are slightly relaxed compared to the LS data lines.
(3) DMD LS signals are single ended.
(4) Mismatch variance for a signal group is always with respect to the reference signal.
(5) DMD HS data lines are differential, thus these specifications are pair-to-pair.
