SI3018-F-GS

Telecom Overview

The Skyworks Solutions Inc. SI3018-F-GS is a line-side device within the Si3050+Si3011/18/19 Voice DAA chipset, designed for globally-compliant foreign exchange office (FXO) analog interfaces. It utilizes patented isolation capacitor technology to eliminate costly isolation transformers while providing superior surge immunity. The component operates on a 3.3 V digital supply voltage with an ambient temperature range of 0°C to 70°C for the F-grade variant. Key electrical specifications include a dynamic range of 80 dB, transmit/receive full-scale levels configurable at +6 dBm or +3.2 dBm, and loop current monitoring capabilities supporting up to 120 mA. It supports standard telephony PCM interfaces and features integrated caller ID support.

• VoIP gateways
• PBX and IP-PBX systems
• Voice mail systems
• DECT base stations

Telecom Procurement Notes

Verify the specific ordering suffix 'F-GS' against the manufacturer's official documentation to confirm package type and temperature grade. Confirm availability status as distribution channels may list this component as discontinued or limited supply. Ensure compliance with RoHS requirements by checking the detailed datasheet specifications for the exact revision.

Telecom Selection Notes

Select the SI3018-F-GS when designing FXO interfaces requiring high surge immunity without discrete isolation components. Consider the F-grade temperature rating (0°C to 70°C) for commercial applications. Pair with the Si3050 system-side device for complete voice DAA functionality. Evaluate power consumption in sleep modes if battery efficiency is critical for the target application.

Telecom Part Context

The SI3018-F-GS belongs to the Si3050+Si3011/18/19 series of programmable voice DAA solutions. It serves as the line-side component in a chipset architecture, working in conjunction with the Si3050 system-side device. This family enables highly-programmable analog interfaces for telephony applications, replacing traditional transformer-based designs with integrated semiconductor solutions.
