Si3050 - Silicon Laboratories

Si3050 PROGRAMMABLE VOICE DAA SOLUTIONS

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 .
