Xignal Technologies reduces VDSL equipment costs by 25%

Xignal’s CMOS-Based Analog Front End (AFE) Intellectual Property (IP) Makes Possible First Single-Chip VDSL Solutions in Industry

Munich, Germany, August 4, 2003 - Xignal Technologies AG, a leading IP solutions provider for the communications semiconductor industry, today announced the release of its CMOS-based mixed signal integrated circuit (IC) AFE design, immediately available for licensing.

This AFE is designed using mainstream pure CMOS process and is available for licensing for usage in the first-ever single-chip solution in the VDSL industry. The new AFE, which is also the first in the industry to include the line driver and lightning protection, reduces system complexity and required real estate on the board. These product features lead to quicker time-to-market and reduced bill of material for new VDSL equipment – ideal for high-volume production.

“The flexibility and performance of our new VDSL AFE makes it agnostic to the choice of VDSL line codes, enabling our customers to move forward regardless of the preferred line code scheme," said Yousif Ammar, President at Xignal. “By making single-chip designs possible for VDSL equipment, the Xignal team has broken a critical barrier to profitable, mass-market penetration of VDSL services worldwide.”

Xignal’s VDSL core family has two products: a dual AFE with line driver (XT20502) intended for DSL access multiplexers (DSLAMs) and a single AFE with line driver (XT20501) for customer premises equipment (CPE).

Due to a patented cancellation technique, an unprecedented distortion and intermodulation specification has been achieved, making it feasible for different line coding schemes to be used. Another unique feature is the provisioning of the full 12 MHz bandwidth in both transmit directions, which allows for standardized or customized frequency plans. CMOS implementation of Xignal’s cores makes it feasible to integrate VDSL CPE with 802.11 Wi-Fi processors on a single die.

Performance and flexibility have been key design objectives for these cores. The high level of integration and integrated adaptive hybrid virtually eliminates the need for all external discrete components with the exception of the line transformer.
