Si3218x Data Short: ProSLIC Single-Chip FXS Solution The Si3218x devices are pin-compatible single-channel ProSLIC products that imple- KEY FEATURES ment a complete foreign exchange station (FXS) telephony interface solution in accord- ance with all relevant global specifications. The Si3218x ProSLIC ICs operate from a 3.3 Complete FXS solution in a single 5x6 mm V supply and interface to standard PCM/SPI or 3-wire ISI digital interfaces with 3.3 V or or 6x6 mm package 1.8 V I/O. The Si3218x integrated dc-dc controller automatically generates the optimal Performs all BORSCHT functions battery voltages required for each linestate. Si3218x ICs are available with voltage rating Ideal for short to medium loops of 106 V. The Si3218x devices are available in a 5x6 mm 36-pin QFN package and a 6x6 mm 40-pin QFN Package.
