X2 10 Gbps System FEATURES AND SPECIFICATIONS Molex’s X2 Pluggable Copper Transceiver meets broad market demands for high-speed interconnects in distances up to 15 meters Molex’s X2 copper transceiver is designed for high-speed, 10 Gigabit Ethernet applications. The transceiver design is based on a 3.125 Gbps XAUI (10 Gigabit Attachment Unit Interface) to XAUI re-timer, with transmit pre-emphasis and receive equalization. This design ensures the signal can be boosted to compensate for signal loss at high frequencies. Preemphasis is achieved by boosting the high-frequency content of a transmitted signal or attenuating lowfrequency content to compensate for high-frequency loss in the cable assembly. Receiver equalization is a similar process applied to the receiver. The re-timer also incorporates clock and data recovery as well as XAUI lane alignment. 74735 Transceiver 74744 Rail The Molex X2 transceiver utilizes an industry standard 10Gbase CX4 cable interface (LaneLink Series 74526) and combines with the X2 guide rail (Molex Series 74744) and 70-circuit X2 connector (Molex Part 74441-0013) for a total system solution. The Molex pluggable 10 Gbps transceiver meets Gigabit Ethernet standards IEEE 802.3ak for CX4 and IEEE 802.3ae for XAUI. The die-cast guide frame provides transceiver retention and a sturdy transmit-to-receive interface.
