Electrical connector for conveying signals between two circuit boards

An electrical connector for conveying signals between a first circuit board and a second circuit board, said electrical connector comprising:

• a first connector portion including a first array of board contacts for connection to a first corresponding footprint on said first circuit board;
• and
• a second connector portion including a second array of board contacts for connection to a second corresponding footprint on said second circuit board;
• wherein said signals include a plurality of signal groups each including a different plurality of related signals, wherein each of said plurality of signal groups is assigned to a grouping of related board contacts of said first array of board contacts and to a corresponding grouping of related board contacts of said second array of board contacts;
• and
• wherein when said first connector portion and said second connector portion are mated, each grouping of related board contacts of said first array is electrically coupled to said corresponding grouping of related board contacts in a transposed location in said second array.

A system for conveying signals between circuit boards comprising:

• a first circuit board including:
• a first connector portion including a first array of board contacts for connection to a first corresponding footprint on said first circuit board;
• and
• a first integrated circuit configured to transmit a first grouping of source synchronous signals and a second grouping of source synchronous signals;
• wherein said first grouping of source synchronous signals is assigned to a first grouping of related board contacts of said first array of board contacts and said second grouping of source synchronous signals is assigned to a second grouping of related board contacts of said first array of board contacts;
• a second circuit board including:
• a second connector portion including a second array of board contacts for connection to a second corresponding footprint on said second circuit board;
• and
• a second integrated circuit configured to receive said first grouping of source synchronous signals and said second grouping of source synchronous signals;
• wherein when said first connector portion and said second connector portion are mated, said first grouping of related board contacts and said second grouping of related board contacts of said first array are electrically coupled to a corresponding first grouping of related board contacts and a corresponding second grouping of related board contacts in a transposed location in said second array.
