Applications DSL IADs Voice mail systems Package Options VoIP gateways DECT base stations PBX and IP-PBX systems Si3050 Description CS 1 18 GND The Si3050+Si3011/18/19 Voice DAA chipset provides a highly-programmable FSYNC 2 17 VDD and globally-compliant foreign exchange office (FXO) analog interface. The solution implements Skyworks Solutions patented isolation capacitor technology, PCKLK 3 16 VA Si3050 Top View DTX 4 15 C1A which eliminates the need for costly isolation transformers, relays, or opto- isolators, while providing superior surge immunity for robust field performance. DRX 5 14 C2A GND The Voice DAA is available as a chipset, a system-side device (Si3050) paired RGDT 6 13 RESET 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.
