AUSTIN, Texas -- Silicon Laboratories Inc. (Nasdaq: SLAB) today announced the Si3110, the industry's smallest, high-performance, integrated analog front end (AFE) for ADSL and ADSL2+ applications. The Si3110 provides a complete ADSL2+ AFE in less than two square inches of board space dramatically simplifying modem design. The highly integrated Si3110 is the ideal solution for business and residential customer premises equipment (CPE) that supports downstream data rates over 24 Mbps for high-speed data, voice and video over broadband.

Based on Silicon Labs' field-proven Si3101 ADSL AFE, the Si3110 achieves high performance using a patented architecture that includes a programmable DSL hybrid for echo cancellation and noise reduction allowing CPE modem manufacturers to provide higher data rates on longer loops to end users over real-world phone lines. Silicon Laboratories' adaptive hybrid filter technology also allows manufacturers to easily overcome the problems associated with performance degradation caused by bridge taps in the phone line. These advanced features of the Si3110 allow it to pass the performance recommendations of the DSL Forum's WT-085 ADSL Interoperability Test Plan.

"The high level of integration and patented DSL hybrid technology of the Si3110 AFE enable our customers to quickly design and deliver advanced, cost-effective, broadband CPE solutions," said Dave Bresemann, vice president of Silicon Laboratories. "Customers currently using the Si3101 now have a software and hardware compatible solution that enables a migration path to higher speeds in a small footprint."

The Si3110 is software programmable to meet ADSL, ADSL2, ADSL2+ standards (including Annex A, B, C), and TR-048 and WT-085 recommendations using a single set of external components. Silicon Laboratories' AFEs are designed to work in conjunction with a host of widely available DMT processors to provide a complete ADSL CPE solution. The Si3110 is fully supported by Aware Inc., the market-leading licensor of intellectual property for broadband communications.

"As the rapid growth of ADSL continues, there is an increasing need for highly integrated, stand-alone AFE solutions that offer cost and performance advantages to modem developers," said Luke Smithwick, vice president of business development at Aware. "Aware's StratiPHY2+TM core and Silicon Laboratories' AFE are key enablers in the market-leading performance and integration of ADSL2+ solutions."
