The Si3050+Si3018/19 Voice DAA chipset provides a highly-programmable and  
globally-compliant foreign exchange office (FXO) analog interface that is ideal for  
DSL IADs, PBXs, IP-PBXs, and VoIP gateway products. 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  
in one 20-pin TSSOP (Si3050) and one 16-pin TSSOP/SOIC (Si3018/19) and  
requires minimal external components. The Si3050 interfaces directly to standard  
telephony PCM interfaces.
