MOLEX 74739-0001

XPAK 10 Gbps Transceiver
FEATURES AND SPECIFICATIONS
74739
Molex’s XPAK Pluggable Copper Transceiver meets broad market demands for high-speed
interconnects for distances up to 15 meters
Molex’s XPAK 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.
The Molex XPAK transceiver utilizes an industry
standard 10Gbase CX4 cable interface (LaneLinkTM
series 74526) and combines with the XPAK Electro
Magnetic Interference (EMI) guide rail (Z-Axis
Pluggable series 74732) and 70-circuit XPAK 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.
