SI3019-F-FS

Telecom Overview

The SI3019-F-FS is a programmable voice Direct Access Arrangement (DAA) manufactured by Skyworks Solutions Inc. It integrates a codec and a 2- to 4-wire analog hybrid for telecommunications applications. The device supports PCM highway data interfaces with μ-law/A-law companding and features an SPI control interface alongside GCI connectivity. Electrical specifications include a 3.3 V power supply, 80 dB dynamic range for both transmit and receive paths, and selectable TX/RX levels of +6 dBm or +3.2 dBm. It operates within a commercial temperature range of 0°C to 70°C and draws 8.5 mA of supply current. The component is housed in a 16-SOIC surface-mount package.
