Vativ Technologies, Inc., San Diego, Calif., a provider of
innovative DSP-based silicon solutions, has introduced a reduced-cost,
10Gbps stacking link IC to its V10LAN product line; V10LAN is the
industry's first and only family of single-chip 10-Gigabit Ethernet
(GbE) transceivers for full- duplex operation over a single CAT5e
unshielded twisted-pair (UTP) cable. The new VTV1115 chip is targeted
toward 10Gbps stacking links in Gigabit Ethernet switches as a
user-friendly alternative to other technologies that is both easier to
manage and less expensive.
The VTV1115 transceiver allows OEMs of Gigabit Ethernet switching
equipment to implement 10Gbps ring or mesh architecture stacking links
using ubiquitous CAT 5e cable with a standard RJ45 connector. Competing
stacking link solutions use connectors and cables that are expensive and
difficult to implement. In addition to common ring architectures, it is
now much easier to implement advanced stacking architectures such as
mesh stacking with a full duplex 10Gbps throughput, which can
significantly improve switch backbone performance by minimizing the
switching path between two nodes in a network.
"This latest addition to our V10LAN family will further help
drive down the cost of 10-Gigabit Ethernet in the data center,"
said Sreen Raghavan, Vativ Technologies' president and CEO.
"It expands our leadership position in 10-Gigabit Ethernet UTP
transceivers."
The new VTV1115 transceiver is a shorter-reach, reduced-cost
version of Vativ's original V10LAN transceiver announced in March,
the VTV1110. Manufactured in 0.13 CMOS technology, the VTV1115 device
implements 5m stacking link connections over industry-standard UTP
cable. On the host side, its XAUI interface connects directly to
switch-fabric ICs. Besides being able to carry data over CAT 5e cable,
this transceiver allows a greater degree of flexibility in the placement
and routing of the switch on a printed circuit board.
The VTV1115 includes a standard two-wire MDIO (management data
input/output) interface for host management, diagnostic information and
status monitoring. It also includes an IEEE 802.3ae-compliant XAUI
interface. The chip allows the use of a single low-cost 25MHz crystal
oscillator to generate the internal reference clocks.
Whereas the VTV1110 transceiver enables rack-to-rack 10GbE
connections such as switch-to-server, switch-to-router and
server-to-server links -- and is available as a XENPAK copper module and
as a stand-alone chip for implementation in 10GbE NIC cards -- the new
VTV1115 is a shorter-reach solution for interconnecting stackable
equipment and is available in chip form only.
Price and Availability
The VTV1115 transceiver is priced at $75 in 10K quantities.
Customer samples and evaluation modules are available now, with volume
production scheduled for early Q4 of 2005.
