PROGRAMMABLE VOICE DAA SOLUTIONS
Features
Applications
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.
