LVDS INTERCONNECT GUIDELINES
See AN-1108 (SNLA008) and AN-905 (SNLA035) for full details.
• Use 100Ω coupled differential pairs
• Use the S/2S/3S rule in spacings
– S = space between the pair
– 2S = space between pairs
– 3S = space to LVCMOS signal
• Minimize the number of Vias
• Use differential connectors when operating above 500Mbps line speed
• Maintain balance of the traces
• Minimize skew within the pair
• Terminate as close to the TX outputs and RX inputs as possible
Additional general guidance can be found in the LVDS Owner’s Manual - available in PDF format from the TI
