Next-Gen Programmable ProSLIC Devices

Silicon Labs recently introduced a new family of small subscriber line interface circuits (SLICs) that offer high levels of integration and programmability for the VoIP gateway market. The single- and dual-channel Si32x8x ProSLIC family provides a best-in-class subscriber line interface solution for a wide range of VoIP customer premises equipment (CPE) including cable gateways, xDSL integrated access devices, xPON optical network terminals, fiber to the home (FTTH), fiber to the building (FTTB), and wireless fixed terminals.Silicon Labs ProSLIC

The Si32x8x ProSLIC family provides industry-leading configurability to ensure future-proofed one- and two-channel foreign exchange station (FXS) telephony interfaces in a compact, single-chip solution. The ProSLIC devices minimize SLIC power consumption by using flexible, integrated tracking DC-DC controllers that support patent-pending, ultra-low-cost capacitive boost configuration technology. They also reduce power by leveraging Silicon Labs’s patented low-power ringing (LPR) technology and an ultra-low-power 50 mW per channel on-hook mode. Patent-pending smart ringing technology available in dual-channel ProSLIC devices also enables the use of cost-effective power adapters in two-channel CPE designs by typically reducing the required peak current by more than 300 mA.

The Si32x8x family offers single-channel SLICs in QFN package options as small as 5 mm × 6 mm, as well as a very compact 7 mm × 7 mm dual-channel solution. The Si32x8x BOM footprint is only 4.2 cm2 per FXS channel.

Beta samples of the Si32x8x ProSLIC devices and evaluation boards are available now. General samples and production quantities are planned for the first quarter of  2016. Single-channel Si3218x device pricing begins at $1.58 in 10,000-unit quantities. Dual-channel Si3228x 10,000-unit pricing begins at $2.12. The ProSLIC evaluation kit costs $250 and ships with full documentation and Silicon Labs’s ProSLIC GUI software.
