Xignal Technologies sets world record for jitter performance in 10-Gigabit technology : New 10 Gb/s CMOS Transceiver Improves Data Transmission Performance in Local, Metro and Wide-Area Networks

Munich, Germany, February 2, 2004- Xignal Technologies AG, a leading analog IP solutions provider for the communications semiconductor industry, today announced the release of its new 10 Gigabit per second (Gb/s) CMOS transceiver design. The product, which exhibits a transmitted clock jitter of less than 200 fsrms (femto seconds) and no measurable crosstalk between receive and transmit path, sets a new world record in jitter performance for high-speed CMOS designs. All achieved jitter values (jitter tolerance, jitter generation) far exceed SONET/SDH requirements to significantly improve data transport equipment performance and reach.

Xignal's XT38702 10 Gb/s transceiver is designed for applications such as OC-192/STM-64, 10 Gb/s Ethernet or 10 Gigabit Fibre Channel. It is also suitable for 10 Gb/s copper connections in backplane, shelf-to-shelf and rack-to-rack applications.

The XT38702 is a completely integrated transceiver consisting of a limiting amplifier, clock and data recovery (CDR), demultiplexer, clock multiplying unit (CMU) and multiplexer. No additional external components are needed to operate the device, which features a power consumption of less than 1W. Due to the integrated limiting amplifier, the input sensitivity of the 10 Gb/s SerDes (Serializer/Deserializer) is less than 15 mV.

"With the XT38702, Xignal continues to deliver highly sophisticated analog designs to the market," said Holger Hoeltke, Vice President of Marketing at Xignal. "With its unprecedented performance and its CMOS implementation the device may readily be integrated in a System-on-Chip environment or be used as a stand-alone IC for data transport applications."

The XT38702 10 Gb/s transceiver is suitable for data rates from 9.95 Gb/s to 10.7 Gb/s. Several functions, including the power-down modes, have the ability to be programmed via a serial bus interface. The XT38702 10 Gb/s transceiver uses 0.13-µm standard CMOS process which guarantees high performance at a very low power consumption level.

On February 20, Xignal will unveil a white paper detailing its record-setting technology at www.xignal.com/10g/wprequest.htm.
