Description

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.
