SI2415-D-FTR

Overview

The Skyworks Solutions Inc. SI2415-D-FTR 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 -40 °C to 85 °C (G-grade). The device integrates a DSP data pump, modem controller, on-chip RAM/ROM, codec, and direct access arrangement (DAA). It provides connect rates up to 14.4 kbps full-duplex over PSTN using ITU-T V.32bis/V.32 protocols. Total supply current is typically 173 mA at nominal conditions.

Feature Summary

• Integrated Direct Access Arrangement (DAA) providing global telephone line interface compliance
• Supports UART, SPI, or parallel host interfaces with flexible clock options
• Includes Type I and II caller ID decode capabilities
• Firmware upgradeable via EEPROM interface

Applications

• Set-top boxes
• Point-of-sale terminals
• Text and video telephones
• Digital video recorders
• Remote monitoring systems

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm compatibility with the paired Si3018/10 line-side device as per the official chipset combinations listed in the datasheet. Ensure the revision level meets project requirements before finalizing procurement orders.

Selection Notes

Select this model when utilizing the 16-pin SOIC packaging option. Verify protocol support needs; this variant supports up to 14.4 kbps (V.32bis/V.32), whereas higher speeds require different chipset members like the Si2457. Check if the G-grade industrial temperature range (-40 °C to 85 °C) is necessary for the target environment.

Part Context

This component belongs to the ISOmodem family, which includes the Si2457, Si2434, and Si2404 system-side devices. These are sold as chipsets with the Si3018/10 line-side device. The family eliminates the need for separate DSPs, codecs, transformers, and opto-isolators by integrating these functions into a compact solution.

Replacement Considerations
