Overview

Si3218x: ProSLIC® Single FXS Solution ProSLIC® Single-Channel FXS Solutions The Si3218x Single FXS ProSLIC® devices implement a complete foreign exchange station (FXS) telephony interface solution in a single package that conforms to all relevant global specifications.
The Si3218x ProSLIC ICs operate from a 3.
3 V supply and have standard PCM/SPI or 3-wire ISI digital interfaces with 3.
3 V or 1.
8 V I/O.
The Si3218x devices are designed to operate with a capacitive boost tracking battery supply for lower power, cost, and footprint 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 Si3218x devices are available in 5 x 6 mm, 36-pin QFN and 6 x 6 mm, 40-pin QFN Packages.
