Voice DAAs

Voice DAAs – Si3050 + Si3011/18/19

The Si3050 IC extends the market-leading performance of Silicon Labs’ Silicon Direct Access Arrangement (DAA) products into the voice telephony market.
The small-footprint chipset consists of a 20-pin Si3050 (TSSOP) system-side device and either the 16-pin Si3019 (TSSOP) or the 16-pin Si3018 (SOIC) line-side device. The solution utilizes Silicon Labs’ patented capacitive isolation technology that uses low-cost, high voltage capacitors instead of a costly and bulky transformer. The Si3050 contains both a PCM highway/SPI interface for most standard telephony applications as well as a GCI interface for customers with legacy requirements.
