The 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.
The new Le9662 features a shared power supply design that rivals the most efficient power supplies available today, only consuming approximately 51 mW per channel in the low power standby state. The design also enables cost-savings of approximately 30% over alternative power supply configurations. To further reduce development costs, it is provided as a two-layer reference design board.
Microsemi’s residential gateway solutions allow designers to add voice capabilities to customer premises equipment (CPE) and are optimised for short loop, power-sensitive applications. In a 56-pin quad flat no lead (QFN) package pricing starts at $2.70 (1,000).
