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. 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.
