The STLC3055N is a SLIC device specifically designed for wireless local loop (WLL) and ISDN- terminal adaptors (ISDN-TA) and VoIP applications. It has a single supply voltage (from 5.5 V to 12 V), self generate the negative battery by means of an on chip DC/DC converter controller that drives an external MOS switch.
The STLC3055N is a single-chip Subscriber Line Interface Circuit (SLIC) designed specifically for Wireless Local Loop (WLL), Voice over IP (VoIP), and ISDN Terminal Adaptor (ISDN-TA) applications. The device implements all key features of the BORSHT function, including battery reversal with programmable transition time, on-hook transmission, off-hook detection, metering pulse generation, and integrated ringing.
