Functions
The DUSLIC™-xT1 and DUSLIC™-xT2 line interface solution combine analog codec and high voltage
SLICs in a single package with reduced footprint. This unmatched fl exibility and performance
enables CPE Voice applications with optimized design and cost.
The DUSLIC™-xT is the most recent addition to Lantiq´s mature and fi eld-proven Voice CPE product
line. PIN-to-PIN compatible 1 and 2 channel solutions enable customer to design a single
hardware on basis of 2-layer design. Compared to other available devices, DUSLIC™-xT offers full
CO grade transmission performance (concerning ringing, feeding, DTMF generation & detection,
and Caller-ID) with an industrial temperature range. DUSLIC™-xT also 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.
A Best-in Class Bill of Material and the ability to implement designs on a 2-layer PCB allows CPE
system manufacturers to offer voice telephony with CO grade performance and full wideband
(16 kHz/16 bit) support at optimized system cost. Industry leading lowest power consumption,
measured in both on and off-hook conditions, allows to meet stringent Code of Conduct
requirements while using a smaller power supply to further improve system design and cost.
