(1) Minimize crosstalk and match traces on the PCB as close as possible.
(2) Maintain the common mode voltage as close to 1.2 V as possible.
(3) Maintain the absolute input differential voltage as high as possible.
(4) The LVDS open input detection is related to a low common mode voltage only. It is not related to a low-differential swing.
(5) LVDS power 3.3-V supply (VDD33_FPD) noise level should be below 100 mVPP.
(6) LVDS power 1.2-V supply (VDD12_FPD) noise level should be below 60 mVPP.
