SI2415-D-FS

Overview

The Skyworks SI2415-D-FS 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 integrates a DSP data pump, modem controller, on-chip RAM/ROM, codec, and direct access arrangement (DAA). It supports data rates up to 14.4 kbps using ITU-T V.32bis/V.32 protocols and Bell 212A/Bell 103 standards. Communication interfaces include UART, SPI, or parallel connections. The component utilizes flexible clocking options such as a 32.768 kHz oscillator, 4.915 MHz oscillator, or 27 MHz clock input.

Feature Summary

• Integrated Direct Access Arrangement (DAA) providing global telephone line interface compliance
• Supports standard AT command sets and firmware upgrades via EEPROM interface
• Eliminates need for external DSP, transformer, relay, and hybrid components
• Includes Type I and II caller ID decode and DTMF detection/generation capabilities

Applications

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

Procurement Notes

Verify the specific package marking and grade against the datasheet's ordering guide to ensure correct revision. Confirm that the host system provides the required 3.0 V to 3.6 V digital supply voltage. Ensure the application schematic follows the recommended layout guidelines provided in the associated application note to maintain signal integrity and emissions compliance.

Selection Notes

Select this model when a complete modem solution is required without external discrete components. Verify protocol support requirements; this unit supports up to 14.4 kbps, whereas higher speeds require Si2457 or Si2434 variants. Check temperature range specifications if operating conditions exceed commercial limits. Confirm interface compatibility with the host processor, whether UART, SPI, or parallel mode is preferred.

Part Context

This component belongs to the ISOmodem chipset family, which pairs with the Si3018/10 line-side device. The 'FS' suffix indicates a specific tape and reel packaging option for surface-mount assembly. It shares the same functional block diagram and pinout structure as other members like the Si2457 and Si2434, differing primarily in supported data rates and protocol versions.
