Quellan and Molex Double Chassis Throughput for Data Center Equipment
Low Power Analog IC reduces power while doubling throughput
SANTA CLARA, CA -- DesignCon Convention -- February 6th, 2008 - -- Quellan Incorporated, a leader in Noise Cancelling and Signal Integrity ICs, and Molex Incorporated (NASDAQ: MOLX and MOLXA) today announced they have demonstrated robust, low-power data transmission at 6.25 Gbps over 40 inches of copper traces across Molex’s I-TracTM backplane. This is the first industry collaboration to demonstrate very high-speed data transmission using low-power cost efficient analog equalization technology without the use of complex digital signal-processing techniques.
In the demonstration, a complex bit pattern from a signal generator without any transmitter equalization is passed through a 40 inch channel in Molex’s Nelco 4000-12 I-Trac Reference Backplane. The resultant signal is degraded beyond recoverable condition due to PCB losses, before Quellan’s QLx4600 Lane Extender device restores the signal to near pristine condition, guaranteeing a bit-error rate of better than 10-15.
Quellan’s Q:ACTIVE® Technology is widely used in active copper cable interconnects to achieve dramatic improvements in cable reach, power consumption and throughput in today’s data centers. For the first time, the same technology is applied to backplane interconnects, opening exciting opportunities for extending the life of legacy backplanes and allowing the creation of new, cost-effective, high-speed platforms. The 6.25 Gbps data rate makes the solution particularly attractive for the emerging high-density RXAUI 10G Ethernet interconnect initiative.
“We are delighted to extend our on going collaboration with Molex to high-speed backplane applications,” said Gourgen Oganessyan, strategic marketing manager at Quellan. “Integrating our Lane Extender devices onto backplanes and line cards allows for XAUI, RXAUI, SAS, SATA, InfiniBand, and PCI Express systems to be built in lower cost PCB laminates with longer channel reach while utilizing cost-effective, simple ASICs.”
“The Molex I-Trac Reference Backplane is an innovative solution that strengthens our market leadership position and adds to the broad portfolio Molex has of 10 Gbps backplane connectors,” said Ryan Price, product manager, Molex Incorporated. “We are excited to be demonstrating real-world 6.25 Gbps performance of our backplane interconnect technology enabled by Quellan's QLx4600 device.”
The demonstration takes place at DesignCon 2008 in Quellan’s booth (#112).
