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
â S = space between the pair
â 2S = space between pairs
â 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 Ownerâs Manual - available in PDF format from the Texas
Instruments web site at: http://www.ti.com/ww/en/analog/interface/lvds.shtml
