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).
The Si3050 is available in a 20-pin TSSOP or a 24-pin QFN.
The Si3011/18/19 is available in a 16-pin TSSOP, a 16-pin SOIC, or a 20-pin QFN and requires minimal external components.
The Si3050 interfaces directly to standard telephony PCM interfaces.
