Single-Channel FXS Solutions
The Si3219x Single FXS ProSLIC
®
devices implement a complete foreign exchange sta-
tion (FXS) telephony interface solution in a single package that conforms to all relevant
global specifications. The Si3219x ProSLIC ICs operate from a 3.3 V supply and have a
3-wire ISI digital interface with 1.8 to 3.3 V I/O. The Si3219x devices are designed to
operate with a capacitive boost tracking battery supply for lower power, cost, and foot-
print than other tracking supplies in the industry. Self-testing and metallic loop testing
(MLT) are facilitated by the built-in DSP, monitor ADC, and test load. The devices are
available with wideband audio for better-than-PSTN voice quality and DTMF detection.
The Si3219x devices are available in a 4 x 6 mm, 38-pin QFN package.

Figure 2.1. Si3219x Functional Block Diagram
The Si3219x series provides all SLIC, codec, DTMF detection, and signal generation functions needed for one complete analog tele-
phone interface. The Si3219x performs all battery, over-voltage, ringing, supervision, codec, hybrid, and test (BORSCHT) functions; it
also supports extensive metallic loop and self-test capabilities.
The Si3219x supports wideband audio (150 Hz–6.8 kHz) compliant with PKT-SP-HDV-104-120823, and is configurable to support the
full ITU-T-G.722-201209 bandwidth (50 Hz–7 kHz). The wideband mode provides an expanded audio band with a 16 kHz sample rate
for enhanced audio quality.
The Si3219x series supports a 3-wire ISI digital interface.
The Si3219x incorporates a programmable dc-dc converter controller that reacts to line conditions to provide the optimal battery voltage
required for each line-state. Si3219x ICs are available with voltage ratings of –100 V.
Programmable on-hook voltage, programmable off-hook loop current, reverse polarity operation, loop or ground start operation, and on-
hook transmission are supported. Loop current and voltage are continuously monitored by an integrated monitoring ADC.
The Si3219x single ProSLIC devices support ringing with or without a programmable dc offset and can operate in low-power ringing
and adaptive-ringing modes. The available voltage 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-pro-
grammable, allowing a single hardware design to meet global requirements.
