Si3011 Datasheet Programmable Voice Daa Solutions

Manufacturer: Silicon Laboratories

Overview: Si3050+Si3011/18/19 PROGRAMMABLE VOICE DAA SOLUTIONS.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The Si3050+Si3011/18/19 Voice DAA chipset provides a highly-programmable and globally-compliant foreign exchange office (FXO) analog interface.

The solution implements Silicon Laboratories' patented isolation capacitor technology, which eliminates the need for costly isolation transformers, relays, or opto-isolators, while providing superior surge immunity for robust field performance.

The Voice DAA is available as a chipset, a system-side device (Si3050) paired with a line-side device (Si3011/18/19).
