Select parts in the series also implement Skyworks Solutions' 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.
3 V 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 –110 V or –135 V to support a wide range of ringing voltages.
See the Ordering Guide for the voltage rating of each Si3217x version.
The Si3217x is available in a 5 x 7 mm 42-pin LGA package.
The Si3291x is available in a 16-pin SOIC package.
