Si3271x ProSLIC Block Diagram

The Si3217x ProSLIC subscriber line interface (SLIC) devices are the world’s smallest single-chip FXS solutions and the industry's first two-chip FXS+FXO solution. These SLIC solutions also offer the lowest power consumption in the industry.​

An application programming interface (API) is available to accelerate and simplify code development.

The Si3217x is a family of pin-compatible single-channel ProSLIC products that implement a complete foreign exchange station (FXS) telephony interface solution in a single package. 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 3.3 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 linestate. Si3217x ICs are available with voltage ratings of –110 V or –135 V to support a wide range of ringing voltages. The Si3217x is available in a 5 x 7 mm 42-pin QFN package. The Si3291x is available in a 16-pin SOIC package.
