Product Information

Back to top
The Si3218x devices are pin-compatible single-channel ProSLIC® products that implement a complete foreign exchange station (FXS) telephony interface solution in accordance with all relevant global specifications. The Si3218x ProSLIC ICs operate from a 3.3 V supply and interface to standard PCM/SPI or 3-wire ISI digital interfaces with 3.3 V or 1.8 V I/O. The Si3218x integrated dc-dc controller automatically generates the optimal battery voltages required for each line-state. Si3218x ICs are available with voltage rating of –106 V. The Si3218x devices are available in a 5x6 mm 36-pin QFN package and a 6x6 mm 40-pin QFN Package.
