The circuit provides all necessary functions to implement voice telephony in broadband customer premise equipment, allowing manufacturers to use a single design for both single- and two-channel voice line systems.
Measuring just 10x10mm in pin-to-pin compatible single- and dual-channel versions, the device allows system manufacturers to use a single PCB card for one or two voice circuits. A Bill of Materials saving of 30 percent compared to competitor’s legacy solutions 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. 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.
