SI2415-C-GT

Overview

The SI2415-C-GT is a system-side component of the ISOmodem family, functioning as a data modem chipset. It supports data rates from 300 bps to 14.4 kbps and operates on a digital supply voltage (VD) ranging from 3.0 V to 3.6 V. The device accommodates ITU-T standards including V.90, V.34, V.32bis, V.32, V.23, V.22bis, V.22, V.21, Bell 212A, and Bell 103. It features UART, SPI, or parallel host interfaces and integrates a direct access arrangement (DAA). Available in 16-pin SOIC or 24-pin TSSOP packages, it supports commercial (0°C to 70°C) and industrial (-40°C to 85°C) temperature ranges.

Feature Summary

• Integrated Direct Access Arrangement (DAA) providing global telephone line interface compliance
• Supports multiple host communication protocols including UART, SPI, and parallel interfaces
• Capable of automatic rate negotiation and fast connect capabilities
• Firmware upgradeable with support for SMS/MMS 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 the specific package option required for the design, as the SI2415 is available in both 16-pin SOIC and 24-pin TSSOP configurations. Confirm that the ordering suffix corresponds to the desired temperature grade and packaging format. Ensure compatibility with the Si3018/10 line-side device for complete functionality. Check datasheet revision history for any updates to electrical specifications or pin assignments prior to finalizing procurement.

Selection Notes

Select the SI2415-C-GT when designing embedded modems requiring speeds up to 14.4 kbps. This model is suitable for applications needing flexible clock options such as 32.768 kHz, 4.915 MHz, or 27 MHz inputs. Consider the 24-pin version if an integrated codec interface or EEPROM interface is required. Verify power consumption requirements against the typical supply current specifications provided in the datasheet.

Part Context

The SI2415 is part of the Skyworks ISOmodem family, which includes the Si2457, Si2434, and Si2404. These devices are designed to work in conjunction with the Si3018 or Si3010 line-side devices. The family utilizes patented DAA technology to eliminate the need for separate DSPs, transformers, and opto-isolators, offering a compact solution for embedded modem applications.
