SI2415-C-GTR

Overview

The SI2415-C-GTR is a system-side component of the Skyworks 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 an ambient temperature range of -40 °C to 85 °C for the G-grade variant. The device integrates a DSP data pump, modem controller, codec, and direct access arrangement (DAA), eliminating the need for external components such as transformers or opto-isolators. It provides programmable telephone line interfaces compliant with global standards, supporting data rates up to 33.6 kbps over PSTN networks.

Feature Summary

• Integrated Direct Access Arrangement (DAA) providing capacitive isolation exceeding 6000 V and globally-compliant line interface capabilities.
• Supports multiple host communication protocols including UART, SPI, and parallel interfaces for flexible system integration.
• Capable of automatic rate negotiation across various ITU-T and Bell standards, ensuring compatibility with diverse network conditions.

Applications

• Set-top boxes requiring integrated telephony features
• Point-of-sale terminals needing reliable dial-up connectivity
• Text and video telephones for accessibility applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and grade. Confirm that the Si3018/10 line-side device is included in the design, as the Si2415 functions as part of a chipset solution. Ensure compliance with humidity sensitivity levels during storage and handling procedures.

Selection Notes

Select this component when a compact, low-component-count solution for embedded modems is required. The integrated DAA reduces bill of materials complexity by removing the need for separate codecs, transformers, and clocking crystals. Verify that the target application supports the required data rates and protocol standards supported by the Si2415.

Part Context

The SI2415 belongs to the ISOmodem family, which includes the Si2457, Si2434, and Si2404. These devices serve as the system-side portion of a two-chip modem solution, pairing with the Si3018 or Si3010 line-side device. This architecture allows for significant footprint reduction in telecommunications equipment compared to traditional discrete implementations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's latest datasheet for potential obsolescence notices or recommended upgrades within the ISOmodem product line.
