SI3019-F-FM

Telecom Overview

The SI3019-F-FM 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 telephony applications. The device supports PCM highway data interfaces with μ-law/A-law companding and features an SPI control interface alongside GCI connectivity. Key electrical parameters include an 80 dB dynamic range for both transmit and receive paths, a +6 dBm or +3.2 dBm TX/RX level mode, and a 3.3 V power supply requirement. It provides line voltage and loop current monitoring, parallel handset detection, and greater than 5000 V isolation using patented technology.
