SILICON LABS SI32911-A-FSR

The Si3217x is a family of 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. Select parts in the series also implement Silicon Laboratories patented capacitive isolation technology to enable seamless connection to Si3291x series foreign exchange office (FXO) line- side devices. The Si3217x ProSLIC ICs operate from a 3.3V supply and interface to standard PCM/SPI digital interfaces. The Si3217x integrated dc- dc controller automatically generates the optimal battery voltages required for each line- state. Si3217x ICs are available with voltage ratings of - 110V or - 135V to support a wide range of ringing voltages. The Si3217x is available in a 5×7mm 42- pin QFN package. The Si3291x is available in a 16- pin SOIC package.
