Vativ Ships Single Chip 10GigE Transceiver for Copper

Vativ Technologies has begun customer sampling a single-chip 10-Gigabit Ethernet (GbE) transceiver for full-duplex operation over a single CAT5e or CAT6 unshielded twisted-pair (UTP) cable. The chip is designed for OEMs and system vendors developing high-speed Ethernet switches and servers for the enterprise datacenter market.

The V10LAN transceiver is implemented in 0.13 CMOS technology, with the host side supporting an IEEE 802.3ae-compliant 10GbE Attachment Unit Interface (XAUI). Full duplex transmission over UTP cabling is achieved through remodulating the XAUI data by using a multibit-per-baud modulation scheme. Additionally, forward error correction (FEC) coding provides an additional 8dB of coding gain to improve immunity to external noise. On the receiver side, an integrated custom digital signal processor implements high-performance adaptive equalization, echo and NEXT/FEXT cancellation algorithms to enable robust, error-free reception.

The company said its solution costs less than a tenth of an equivalent short-reach optical solution.

"Our V10LAN transceiver enables the use of widely available, low-cost CAT5e and CAT6 cables, as well as off-the-shelf RJ-45 connectors," said Sreen Raghavan, Vativ Technologies' president and CEO.
