X2 10 Gbps System

FEATURES AND SPECIFICATIONS

74735 Transceiver

74744 Rail

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. Pre-

emphasis is achieved by boosting the high-frequency

content of a transmitted signal or attenuating low-

frequency 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.

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.
