The require precise length matching. LVDS data bus differential pairs should have an impedance of 100 Ω (with 5% tolerance). It is important that the propagation delays are matched. The maximum differential pair uncoupled length is 150 mils with a relative propagation delay of ±25 mil between the p and n. Matching all signals exactly will maximize the channel margin. The signal path through all boards, flex cables and internal DMD routing must be considered in this calculation.
