SI3015-FS

Overview

The SI3015-FS is a telecom interface IC designed for voice modems, specifically functioning as an ISOmodem line-side Direct Access Arrangement (DAA). It supports V.90 compliant data transmission and handles baud rates suitable for legacy modem applications. The device operates on a single power supply ranging from 3V to 3.6V with a typical operating current of 8.5mA. It utilizes SPI, parallel, or UART interfaces for control. The component is housed in a 16-SOIC package and is rated for commercial temperatures between 0°C and +70°C.
