SI2415-C-FTR

Overview

The Skyworks Solutions Inc. SI2415-C-FTR is a system-side component of the ISOmodem family, designed for embedded modem applications. It supports data rates up to 33.6 kbps and operates with a digital supply voltage (VD) ranging from 3.0 V to 3.6 V. The device functions within an ambient temperature range of 0 °C to 70 °C (F-grade). Key electrical characteristics include a typical total supply current of 173 mA and a wake-on-ring current of 4.4 mA. It features integrated Direct Access Arrangement (DAA) technology, providing over 6000 V capacitive isolation and global line interface compliance.

Feature Summary

• Integrated Direct Access Arrangement (DAA) technology eliminates the need for external DSPs, codecs, transformers, or opto-isolators.
• Supports standard AT command sets and firmware upgrades via an EEPROM interface.
• Provides flexible clocking options including low-cost 32.768 kHz oscillators, 4.915 MHz oscillators, or 27 MHz clock inputs.
• Includes Type I and II caller ID decode capabilities and DTMF detection/generation.

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 the datasheet validity depends on listed chipset combinations. Ensure the design adheres to the recommended operating conditions for VD and ambient temperature specified in the electrical specifications table.

Selection Notes

Select this model when a complete embedded modem solution with minimal external components is required. It is suitable for designs needing support for ITU-T protocols up to V.34 and Bell standards. Consider the 16-pin SOIC or 24-pin TSSOP packaging options based on board space constraints. Verify that the host interface requirements align with the supported UART, SPI, or parallel interfaces.

Part Context

The SI2415-C-FTR belongs to the ISOmodem family, which includes the Si2457, Si2434, and Si2404 system-side devices. These components are designed to work in conjunction with the Si3018/10 line-side device to form a complete modem chipset. This family utilizes patented DAA technology to provide a programmable telephone line interface with high integration levels.

Replacement Considerations

Public confirmed substitute part numbers: Si2457-D-FT, Si2434-D-FT, Si2404-D-FT. Note that these alternatives may offer different maximum data rates or protocol support compared to the SI2415-C-FTR.
