2. Functional Description
The ProSLIC is a single, low-voltage CMOS device that
provides all SLIC, codec, DTMF detection, and signal
generation functions needed for a complete analog
telephone interface. The ProSLIC performs all battery,
overvoltage, ringing, supervision, codec, hybrid, and
test (BORSCHT) functions. The Si3216 supports
wideband (50 Hz–7 kHz) and narrowband (200 Hz–
3.4 kHz) audio codec modes to provide an expanded
audio band at a 16 kHz sample rate for enhanced audio
quality
as
well
as
standard
telephony
audio
compatibility. The Si3216 is ideal for Customer Premise
Equipment (CPE) where enhanced audio quality is
required.
Unlike most monolithic SLICs, the ProSLIC does not
require
externally-supplied,
high-voltage
battery
supplies. Instead, it generates all necessary battery
voltages from a positive dc supply using its own dc-dc
converter
controller.
Two
fully-programmable
tone
generators can produce DTMF tones, phase continuous
FSK (caller ID) signaling, and call progress tones. Pulse
metering signal generation is also integrated. The
Si3201 linefeed interface IC performs all high-voltage
functions. As an option, the Si3201 can be replaced with
low-cost discrete components.
The linefeed provides programmable on-hook voltage,
programmable off-hook loop current, reverse battery
operation, loop or ground start operation, and on-hook
transmission ringing voltage. Loop current and voltage
are continuously monitored using an integrated A/D
converter. Balanced 5 REN ringing with or without a
programmable dc offset is integrated. The available
offset, frequency, waveshape, and cadence options are
designed to ring the widest variety of terminal devices
and to reduce external controller requirements.
A complete audio transmit and receive path is
integrated, including ac impedance and hybrid gain.
These features are software-programmable, allowing
for
a
single
hardware
design
to
meet
global
requirements. Digital voice data transfer occurs over a
standard PCM bus. Control data is transferred using a
standard SPI. The device is available in a 38-pin QFN or
TSSOP.
2.1. Linefeed Interface
The ProSLIC’s linefeed interface offers a rich set of
features and programmable flexibility to meet the
broadest application requirements. The dc linefeed
characteristics are software programmable; key current,
voltage, and power measurements are acquired in real
time and provided in software registers.
2.1.1. DC Feed Characteristics
The ProSLIC has programmable constant voltage and
constant current zones as depicted in Figure 16. Open
circuit TIP-to-RING voltage (VOC) defines the constant
voltage zone and is programmable from 0 V to 94.5 V in
1.5 V steps. The loop current limit (ILIM) defines the
constant current zone and is programmable from 20 mA
to 41 mA in 3 mA steps. The ProSLIC has an inherent
dc output resistance (RO) of 160 .
Figure 16. Simplified DC Current/Voltage
Linefeed Characteristic
The TIP-to-RING voltage (VOC) is offset from ground by
a programmable voltage (VCM) to provide voltage
headroom to the positive-most terminal (TIP in forward
polarity states and RING in reverse polarity states) for
carrying
audio
signals.
Table 21
summarizes
the
parameters to be initialized before entering an Active
state.
