SI2415-D-FT

Overview

The Skyworks Solutions Inc. SI2415-D-FT 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 data rates up to 14.4 kbps over PSTN. The device integrates a DSP data pump, modem controller, codec, and direct access arrangement (DAA). It supports ITU-T protocols including V.90, V.34, V.32bis, V.32, V.29, V.22, V.22bis, and V.21, as well as Bell 212A and Bell 103 standards. Available in a 16-pin SOIC package, it facilitates UART, SPI, or parallel host interfaces.

Feature Summary

• Integrated Direct Access Arrangement (DAA) providing global telephone line interface compliance
• Supports standard AT command sets and firmware upgrades via EEPROM interface
• Includes Type I and II caller ID decode capabilities
• Offers flexible clocking options using low-cost oscillators or external inputs

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Confirm chipset compatibility with the Si3018 line-side device before integration. Check for product change notifications regarding pin assignments or electrical specifications prior to final design approval.

Selection Notes

Select this model when a compact 16-pin solution is required for embedded modems supporting speeds up to 14.4 kbps. Ensure the application environment matches the specified commercial or industrial temperature ranges. Verify that the host processor can support the available UART, SPI, or parallel communication interfaces defined in the datasheet.

Part Context

This component belongs to the ISOmodem family, which includes the Si2457, Si2434, and Si2404. These devices function as system-side counterparts to the Si3018/10 line-side devices. The family utilizes patented DAA technology to eliminate the need for separate DSPs, transformers, and hybrid circuits in telephone interface designs.
