AnSem's wired communication technology extends from multi gigabit serial data links to broadband wired communication for multi-media home networks offering more than 200Mbps bandwidth to the user.

Our Serialiser and Deserialiser (SerDes) technology has been embedded in ASICs complying with SONET and XAU standards, while our fully integrated Analog Front-End (AFE) for the multimedia home market complies with standards like HomePNA, Moca and G.Hn. These ASICs can be connected to any type of cable: phone line, coax and powerline or proprietary cables in industrial, automotive or aerospace markets.

AnSem's success lies in its in-depth system level understanding of the application and its proprietary design techniques, using in-house developed tools that can map a system level specification like SINAD onto noise and linearity specifications for the underlying blocks. Complex 1024 QAM modulation with OFDM can as such be mapped onto the best suited architecture, delivering the required high linearity and low noise performance. The RX and TX paths are complemented by best-in-class ADCs and DACs.
