描述 Description

The Si3210/11 ProSLIC? chipset provides a complete analog telephone interface ideal for customer premise equipment (CPE). It integrates a subscriber line interface circuit (SLIC), voice codec, and battery generation (Si3210) or battery selection (Si3211) into a single CMOS integrated circuit. The battery supply continuously adapts its output voltage to minimize power dissipation and enables the entire circuit to be powered from a single 3.3 or 5 V supply (Si3210). The CMOS ProSLIC interfaces to the line
