Description
The ProSLIC
telephone interface ideal for customer premise equipment (CPE) applications. The
ProSLIC integrates a subscriber line interface circuit (SLIC), codec, and battery
generation functionality into a single CMOS integrated circuit. The integrated battery
supply continuously adapts its output voltage to minimize power and enables the entire
solution to be powered from a single 3.3 V (Si3210M/Si3211M only) or 5 V supply. The
ProSLIC controls the phone line through Silicon Labs’ Si3201 Linefeed Interface Chip.
Si3210 features include software-configurable 5 REN internal ringing up to 90 V
DTMF generation and decoding, and a comprehensive set of telephony signaling
capabilities for operation with only one hardware solution. The ProSLIC is packaged in
a 38-pin QFN and TSSOP, and the Si3201 is packaged in a thermally-enhanced 16-pin
SOIC.
