SI2415-D-FSR

Modems - ICS And Modules Overview

The Skyworks Solutions Inc. SI2415-D-FSR is a system-side component of the ISOmodem family, designed for embedded modem applications. It operates with a digital supply voltage (VD) ranging from 3.0 V to 3.6 V and supports ambient temperatures from 0 °C to 70 °C (F-grade). The device provides data rates up to 14.4 kbps using ITU-T V.32bis or V.34 protocols. It features an integrated Direct Access Arrangement (DAA) offering over 6000 V capacitive isolation and global line interface compliance. Total supply current is typically 173 mA at nominal conditions, dropping to 80 µA in power-down mode. The component utilizes UART, SPI, or parallel interfaces and is housed in a 16-pin SOIC package.

Modems - ICS And Modules Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the revision level against the manufacturer's latest documentation to ensure compatibility with the intended Si3018/10 line-side device chipset combination. Check for any recent product change notices regarding pin assignments or electrical specifications before finalizing procurement orders.

Modems - ICS And Modules Selection Notes

Select this model when designing embedded modems requiring a compact footprint without separate DSPs or transformers. Ensure the host system supports the available interface modes (UART, SPI, or parallel). Verify that the application environment stays within the specified F-grade temperature range. Confirm that the required maximum data rate aligns with the device's 14.4 kbps capability.

Modems - ICS And Modules Part Context

This component belongs to the ISOmodem family, which combines system-side devices like the Si2415 with line-side devices such as the Si3018. The family eliminates the need for external codecs, relays, and hybrid circuits. The Si2415 specifically targets applications needing reliable PSTN connectivity with minimal external components, serving as a complete solution for voice and data transmission over standard telephone lines.
