SI2415-D-GT

Overview

The Skyworks Solutions SI2415-D-GT 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 supports data rates up to 14.4 kbps using ITU-T V.34 or V.32bis protocols and offers 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
• Features flexible clocking options including low-cost oscillators or external clock inputs

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 option, as the datasheet covers both 16-pin SOIC and 24-pin TSSOP variants within the same document. Confirm the temperature grade (F or G) aligns with the target operating environment. Ensure the Si3018 line-side device is included in the design, as the SI2415 functions as part of a chipset solution.

Selection Notes

Select the SI2415 when the application requires data speeds up to 14.4 kbps using V.34 or V.32bis protocols. Choose this model over the Si2457 if higher speeds like V.90 are not needed. Verify the necessary host interface (UART, SPI, or parallel) and ensure the chosen package size fits the PCB footprint constraints.

Part Context

The SI2415 is one of four system-side devices in the ISOmodem family, alongside the Si2457, Si2434, and Si2404. It is specifically designed to pair with the Si3018 line-side device. This combination eliminates the need for separate DSPs, codecs, transformers, and opto-isolators, offering a compact solution for embedded modems.

Replacement Considerations

Public confirmed substitute part numbers: Si2434-D-GT, Si2404-D-GT.
