Description
The Si3210/11
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
through either the Si3201 Line-feed IC or a discrete line-feed circuit.
Si3210/11 features include software-configurable 5 REN internal ringing up to 90 VPK,
DTMF generation and decoding, Caller ID generation, and a comprehensive set of
telephony signaling capabilities for global operation with a single hardware solution.
The Si3210/11 is packaged in a 38-pin QFN or TSSOP, and the Si3201 is packaged in
a thermally-enhanced 16-pin SOIC.

Notes:
1.
Permanent device damage may occur if the absolute maximum ratings are exceeded. Functional operation should be
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 °C 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.
The input signal level should be 0 dBm0 for frequencies greater than 100 Hz. For 100 Hz and below, the level should
be
–10 dBm0. The output signal magnitude at any other frequency will be smaller than the maximum value specified.
2.
Analog signal measured as V

RING
. Assumes ideal line impedance matching.
3.
The quantization errors inherent in the µ/A-law companding process can generate slightly worse gain tracking
performance in the signal range of 3 to –37 dB for signal frequencies that are integer divisors of the 8 kHz PCM
sampling rate.
4.
The level of any unwanted tones within the bandwidth of 0 to 4 kHz does not exceed –55 dBm.
5.
Assumes normal distribution of betas.
