The Dual ProSLIC is a low-power subscriber line interface circuit (SLIC) solution that integrates two SLICs and two codecs into a tiny CMOS IC to provide the smallest and lowest cost dual-channel analog telephone interface.
Fully programmable parameters allow global compliance using a single hardware solution and on-chip functions such as DTMF generation/decoding, FSK caller ID generation and modem tone detection help eliminate external DSP requirements. Integrated test and line monitoring allows remote subscriber loop and line card diagnostics without centralized test equipment.
