Honored ContributorCould some one explain some thing in this schematic please :)

Honored ContributorI might be mistaken but it seems like those pins correspond to differential pairs (see lvds (http://en.wikipedia.org/wiki/low-voltage_differential_signaling)) where one is high and another one is low.
