Description

The Si32260/1 Dual ProSLICÂ® devices, in a single package, implement two complete foreign exchange station (FXS) telephony interfaces. The Si32260/1 devices operate from a 3.3 V supply
and have standard PCM/SPI or GCI bus 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.
