ProSLIC® Single-Channel FXS Solutions

The Si3219x 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 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 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 Si3219x devices are available in a 4 x 6 mm, 38-pin QFN package.

Applications:
• VoIP Gateways and Routers
• xDSL IADs
• Optical Network Terminals/Units (ONT/U)
• Analog Terminal Adapters (ATA)
• Cable eMTA
• Wireless Fixed Terminals (WFT)
• Wireless Local Loop (WLL)
• WiMAX CPE

Symmetry Electronics is an authorized Silicon Labs distributor.
