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.
