A routing structure for a transceiver core, the routing structure including a transmitter block design and a receiver block design. The transmitter block design includes two dedicated transmitter power contacts, two common ground contacts, and two transmitter signal contacts in a transmitter differential pair. The two transmitter signal contacts are both adjacent each of the two dedicated transmitter power contacts and each of the two common ground contacts. The receiver block design includes two dedicated receiver power contacts, two common ground contacts, and two receiver signal contacts in a receiver differential pair. The two receiver signal contacts are both adjacent each of the two dedicated receiver power contacts and each of the two common ground contacts.
