10.1.4.1 Trace Length Matching

The DLPC410 DMD data signals require precise length matching. Make sure differential signals have impedance of 100 Ω (with 5% tolerance). It is important that the propagation delays are matched. The maximum differential pair uncoupled length is 100 mils with a relative propagation delay of ±25 mil between the p and n. Matching all signals exactly maximizes the channel margin. The signal path through all boards, flexible cables and internal DMD routing must be considered in this calculation.
