Looking to simplify design and reduce system cost, for voice telephony on xDSL, fiber and cable gateways? The Lantiq™ DUSLIC™-xT, with its advanced features and superior power efficiency, is an ideal solution for boosting performance while decreasing power consumption and reducing system costs. 

The new DUSLIC™-xT is a low-power single-chip CODEC/SLIC™ for voice terminal and VoIP-enabled PC applications. The DUSLIC™-xT is designed to address the key challenges facing voice terminal system designers, including power consumption, power dissipation, system footprint and Bill-Of-Materials (BOM) costs. In addition, it incorporates a range of new value-added features, such as wideband audio and loop monitoring, to allow system designers to differentiate products from their competition.

As communications service providers continue the transition to xDSL, fiber and cable-based broadband, standard telephone line termination in broadband gateways has become an essential part of next generation network deployments, resulting in growth for the voice line interface. Lantiq’s single package solution enables optimization of system design and costs by providing unmatched flexibility and performance. 

• Size: the DUSLIC-xT, measures just 10x10 mm in pin-to-pin compatible single- and dual-channel versions, allowing system manufacturers to use a single PCB card for one or two voice circuits
• Cost Savings: BoM savings of  30% vs legacy solutions provided by competition and the ability to implement designs on a 2-layer PCB allows system manufacturers to offer systems with voice telephony with Central Office grade performance and full wideband (16 kHz/16 bit) support at optimized system cost
• Power: With industry leading lowest power consumption, measured in both on and off-hook conditions, system manufacturers can meet stringent Code of Conduct requirements while using a smaller power supply to further improve system design and cost
• Standards: DUSLIC-xT supports industry standard (GR-909) line test requirements and additional unique tests such as electronic ring detection to validate lines that have no handset attached

The new DUSLIC-xT devices in a VQFN-88 package are available now for development and system production.  Evaluation boards, as well as several reference designs, are available to speed integration with a wide range of xDSL, fiber and cable modem network processor solutions.
