Description
The Si3050+Si3011 Voice DAA chipset provides a highly-programmable 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 (Si3011) and requires
minimal external components. The Si3050 interfaces directly to standard
telephony PCM interfaces.
