VE8911-HV
Single Channel High Voltage FXS + 1 FXO
Product is discontinued and not allowed for new designs.
Overview
The VE8911-HV chip set is a highly integrated, low-cost, 1FXS + 1FXO chip set that is optimized for residential VoIP gateways such as voice enabled DSL modems, set-top boxes, and analog terminal adapters.The chip set implements simultaneous FXS and FXO functionality by providing the necessary voice interface functions to connect to and power a telephone and an isolated DAA for connection to the PSTN. On the digital side, the VE8911-HV chipset provides standard MPI and PCM interfaces to a VoIP processor.
The VE8911-HV chip set, coupled with the 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 the devices from application code while providing functions for controlling, supervising, and testing a set of subscriber lines. The chip set utilizes patented low value PCB capacitors, resulting in best in class DAA performance in both common mode and RF immunity. |
