SI32260-C-FM Product Details

The Si3226x Dual ProSLIC® devices, in a single package, implement two complete foreign exchange station (FXS) telephony interfaces. The Si3226x devices operate from a 3.3 V supply. The Si32260/1 have standard PCM/SPI or GCI bus digital interfaces, while the Si32266/7 devices use our proprietary three-wire digital Integrated Serial Interface (ISI). 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.
