Transceiver tackles 10Gbit-CX4 Ethernet

Fujitsu Components Europe has released a copper electrical transceiver module compliant with the X2 multisource agreement specification Rev 1.0b.

Fujitsu Components Europe has released a copper electrical transceiver module compliant with the X2 multisource agreement (MSA) specification Rev 1.0b.

The X2 x-mGC module transmits 10Gbit/s Ethernet over 20m of standard InfiniBand copper cable (AWG24) or VSR parallel optics through a single port, offering a cost-effective, standards-compliant product targeted for multiple applications in 10Gbit/s enterprise, storage and telecomms markets.

Using the embedded media detect circuit, transmission up to 300m over standard multimode fibre can also be achieved using Fujitsu's o-MGC optical media convertor.

Based on Fujitsu's industry-standard microGiGaCN copper differential I/O connector, Fujitsu's X2 x-mGC module incorporates the complete physical layer functionality from the system side XAUI-compliant (four lanes at 3.125Gbit/s) four differential electrical interface to the front panel CX4-compliant microGiGaCN electrical interface.

Half the size of a Xenpak module, the hot-pluggable X2 x-mGC module reduces occupied board space on line cards.

Fujitsu is offering it in low-pak, mid-pak and hi-pak form factors as defined in the X2 MSA.

First offering will be the mid-pak form factor, followed by the low-pak for PCI applications.

The X2 x-mGC features an integrated control interface (MDIO) and includes CX4 transmitter and receiver ports.

The mux/demux, XAUI interface and MDIO management functions are all integrated into the module, as is a precision oscillator that eliminates the need for an external reference clock.

The host may control the X2 registers using the XAUI interface as defined in the X2 MSA.

The X2 module supports link alarm status interrupt.

Total power consumption is less than 3.0W, and impedance is 100ohm differential, AC-coupled I/O.
