SI3018-KT - Brand New SILICON LABS Telecommunication Interface ICs
-
Description
The SI3018-KT is a Voice Direct Access Arrangement (DAA) telecommunication interface IC. It is a part of the multinational tech firm Silicon Laboratories' Si3050+Si3011/18/19 Voice DAA chipset that provides a robust and highly-programmable analog interface. It employs Silicon Laboratories patented isolation capacitor technology, which eliminates the requirement for expensive isolation transformers, relays, or opto-isolators while providing superior surge immunity. The Voice DAA is available as a chipset, a system-side device (Si3050) combined 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 SI3018-KT directly interfaces with standard telephony PCM interfaces.
