Overview
We are transitioning to Microchip; this page will be directed to Le89156 product page at www.microchip.com.
The Le89156 is a cost-optimized 1FXS device for residential VoIP gateways such as voice enabled DSL modems, set-top boxes, and analog terminal adapters.
The device implements FXS functionality by providing the necessary voice interface functions to connect to and power a telephone. On the digital side, the Le89156 provides standard MPI and PCM interfaces to a VoIP processor. The Le89156, coupled with Microsemi's VoicePath API-II (VP API-II) enables designers to offer a single hardware design that is software programmable for worldwide markets. The VP API-II 'C' code is used to abstract Microsemi devices from application code while providing functions for controlling, supervising, and testing a set of subscriber lines. |
