Hi Jeff, If you are using a backplane then Teradyne-HSD connectors work great but if you are going with cables then SMA -SMA coaxial work good too. Agilent offers matched cable pairs with skew less than 25ps. Apart from that Joy signal (www.joysignal.com) also make matched pairs with skew less than 15ps . You should definately go with matched pairs for LVDS. The cables are pricey but definately worth it.

The length of the cable would be about 2" between boards and the trace on each PCB to the SerDes would be <3" for a total length of 8". Any suggestions, solutions or pointers would be greatly appreciated.
