Programmable SLIC for advanced voice-over-IP
Silicon Labs' latest family of subscriber line interface circuits (SLICs) offers the lowest power consumption, smallest footprint, and highest levels of integration and programmability for the voice-over-IP (VoIP) gateway market.

The ProSLIC application programming interface (API), a common software library for the entire ProSLIC portfolio, eliminates the need to develop system-specific software drivers for ProSLIC devices. The ProSLIC API incudes example Linux kernel and userspace device driver examples to further reduce development time. The API supports a rich set of metallic loop tests to diagnose external faults, as well as a set of inward self-tests to support diagnostics. Reference design hardware and software support is available from leading vendors of SoC solutions for VoIP gateway equipment.

Beta samples of the Si32x8x ProSLIC devices and evaluation boards are available now. Single-channel Si3218x device pricing begins at $1.58 (10,000)-unit quantities, and dual-channel Si3228x 10,000 pricing begins at $2.12. The ProSLIC evaluation kit is priced at $250.00
