(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.
