ProSLIC® Single-Chip Dual FXS Solution
The Si3229x Dual ProSLIC® devices, in a single package, implement two complete foreign exchange station (FXS) telephony interfaces. The Si3229x devices operate from a 3.3 V supply and have standard PCM/SPI or 3-wire ISI digital interfaces. A pair of built-in dc-dc converter controllers can be used to automatically generate the optimal battery voltage required for each line-state, optimizing efficiency and minimizing heat generation. The Si3229x devices are designed to operate with capacitive ultra-boost tracking battery supply for lower power, cost, and footprint vs. other tracking or shared battery supplies in the industry.
