Microsemi recently introduced the miSLIC Series of line circuits designed to provide network operators with an economical solution for adding two channels of voice to broadband products including residential gateways, DSL integrated access devices (IADs), cable embedded multimedia terminal adapters (eMTAs) and fibre-to-the-premise (FTTX) solutions.

The new Le9662 and Le9672 are designed for applications requiring shared or individual power supplies. Both miSLIC Series line circuits support ringing and system power management, enabling energy efficient control of two telephone lines for meeting the European Code of Conduct on Energy Consumption of Broadband Equipment specifications. The new solutions are also compatible with processors developed by leading system-on-chip (SoC) vendors for residential gateway applications.

"Microsemi's new miSLIC Series line circuits and shared buck boost power supply are a winning combination for adding two channels of voice to VoIP enabled broadband gateways," said Nigel Wakley, director of marketing for Microsemi's Voice product group. "With more than 900 million voice line circuits shipped to customers globally, Microsemi continues to build on its leadership position in this segment by delivering innovative new products that provide our customers with a competitive edge."

The new Le9662 features a patent-pending shared power supply design that rivals the most efficient power supplies available today, only consuming approximately 51 milliwatts of power per channel in the low power standby state. The design also enables cost-savings of approximately 30 per cent over alternative power supply configurations. To further reduce development costs, the solution is provided as an economical two-layer reference design board.

Microsemi's residential gateway solutions allow customers to add voice capabilities to customer premises equipment (CPE) easily and cost-effectively. These products deliver the highest levels of integration available today and are optimised for short loop, power-sensitive applications. Microsemi also offers an extensive application toolset to complement these devices, including software development tools, reference designs and development platforms, to speed time-to-market.

The miSLIC Series solutions are available in a 56-pin quad flat no lead (QFN) package and are sampling now. Pricing starts at $2.70 in 1,000 unit quantities.
