SI32172-C-GM1R

Si3217x-C ProSLIC® Single-Chip FXS Solutions Description - The Si3217x devices are pin-compatible single-channel ProSLIC products that implement a complete foreign exchange station (FXS) telephony interface solution in accordance with all relevant LSSGR, ITU, and ETSI specifications. The Si3217x ProSLIC ICs are available in a 5x7 mm 42-pin QFN package and operate from a 3.3 V supply and support 3.3 V and 1.8 V I/O. The Si32170/1/6/7 devices use a standard PCM/SPI digital interface to connect to SoCs, while the Si32172/3/5 devices use Silicon Labs' proprietary three-wire digital Integrated Serial Interface (ISI) to connect to SoCs with the ISI pre-integrated. The Si3217x integrated dc-dc controller automatically generates the optimal battery voltages required for each line state. The Si3217x ICs are available with voltage ratings of –110 V or –140 V to support a wide range of ringing voltages. See the Ordering Guide for the voltage rating of each Si3217x version.
