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.
