Compliant with IEEE802.3ak (10GBASE-CX4)
X2 MSA Rev 1.0b Compatible module
Industry standard electrical connector, microGiGaCNTM (I/O interface)
XAUI Four channel electrical interface (Host side card edge)
XAUI Standard 70 pin connector for host connection
Front panel hot swap ability.
X2 MSA Rev 1.0b compliant MDIO
Link Alarm Status Interrupt (LASI) support
Total Power consumption under 3.0 watt
20 meters over standard InfiniBand copper cable (24AWG)
With media detect converter (o-mGC), up to 300 meters over standard multi mode fiber.
No external clocks requirement – oscillator on board
Description
The x-mGC is a 10Gigabit Ethernet CX4 Module that designed to ease X2 MSA Rev 1.0b and it is an
electrical module that incorporates the complete physical layer functionality from XAUI compliant 4 lanes x
3.125 Gb/s four differential electrical interface to the microGiGaCN™ CX4 compliant electrical interface.
The x-mGC is plugged into a X2 hosting system and connects to a 4X InfiniBand cable. The control interface
(MDIO)is also integrated. The x-mGC module includes 10Gb/s Ethernet transmitter and receiver ports. The
host may control the x-mGC registers using XAUI interface as defined in the X2 MSA. The MUX/DEMUX,
XAUI interface and MDIO management functions are all integrated into the module, as is a precision
oscillator that removes any need for an external reference clock.
