PROSLIC® PROGRAMMABLE WIDEBAND SLIC/CODEC
WITH RINGING/BATTERY VOLTAGE GENERATION
Features
Applications
Description
The Si3216 ProSLIC
®
is a low-voltage CMOS device that provides a complete analog
telephone interface supporting both wideband (50 Hz to 7.0 kHz) and narrowband
(200 Hz to 3.4 kHz) audio codec modes for enhanced voice quality in Voice-over-IP
(VoIP) applications. The ProSLIC integrates subscriber line interface circuit (SLIC),
wideband voice codec, and battery generation functionality into a single fully-
programmable device for global operation using only one hardware solution. The
Si3216’s wideband codec provides expanded audio band (50 Hz to 7 kHz), 16 kHz
sampling rate, and increased dynamic range for improved audio quality over traditional
telephony codecs. 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
(Si3216M only) or 5 V supply. Si3216 features include software-configurable 5 REN
internal ringing up to 90 V
PK
, DTMF and caller ID generation, and a comprehensive set
of telephony signaling capabilities including expanded support of Japan and China
country requirements. The ProSLIC is packaged in a 38-pin QFN and TSSOP, and the
Si3201 high-voltage line interface device is packaged in a thermally-enhanced 16-pin
SOIC.

restricted to the conditions as specified in the operational sections of this data sheet. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
2. Operation above 125 ºC junction temperature may degrade device reliability.
3. Thermal resistance assumes a multi-layer PCB with the exposed pad soldered to a topside PCB pad.

Notes:
1. VDDD, VDDA =3.3V.
2. VDDD, VDDA =5.25V.
3. IBAT = current from VBAT (the large negative supply). For a switched-mode power supply regulator efficiency of 71%,
the user can calculate the regulator current consumption as IBAT x VBAT/(0.71 x VDC).
