Abstract:
1. A ball grid array (BGA) package, comprising: an integrated circuit (IC) packaged in the BGA package configured to process a first signal, a second signal, a third signal, and a fourth signal, the first signal and the second signal being a first pair of differential signals and the third signal and the fourth signal being a second pair of differential signals; a first solder ball configured to conduct the first signal disposed on a surface of the BGA package; a second solder ball configured to conduct the second signal disposed on the surface of the BGA package; a third solder ball configured to conduct the third signal disposed on the surface of the BGA package; a fourth solder ball configured to conduct the fourth signal disposed on the surface of the BGA package, wherein the third solder ball has a first equal distance from the first solder ball and the second solder ball, the fourth solder ball has a second equal distance from the first solder ball and the second solder ball, and the first solder ball and the second solder ball are in symmetry with regard to the third solder ball; and a plurality of grounded solder balls coupled to the IC for ground connections including a first grounded solder ball, a second grounded solder ball, a third grounded solder ball, and a fourth grounded solder ball, wherein the first grounded solder ball is disposed adjacent to the first solder ball, the second grounded solder ball is disposed adjacent to the second solder ball, the third grounded solder ball is disposed adjacent to the third solder ball, the fourth grounded solder ball is disposed adjacent to the third solder ball, the first and the third grounded solder balls are disposed on a line that intersects the first and the third solder balls, and the second and the fourth grounded solder balls are disposed on a line that intersects the second and the third solder balls.
