SI3050-E1-GT

Telecom Overview

The Skyworks Solutions SI3050-E1-GT is a system-side device within the Si3050+Si3011/18/19 Voice DAA chipset, designed for highly-programmable and globally-compliant foreign exchange office (FXO) analog interfaces. Operating on a 3.3 V supply with a G-Grade temperature range of -40°C to +85°C, it features an integrated codec, 2- to 4-wire analog hybrid, and patented isolation capacitor technology that eliminates bulky isolation transformers. The component supports PCM highway and GCI interfaces, offering 80 dB dynamic range, programmable digital gain in 0.1 dB increments, and Type I/II caller ID support.

Telecom Feature Summary

• Patented isolation capacitor technology providing superior surge immunity without requiring costly isolation transformers or relays
• Integrated codec and programmable digital hybrid for near-end echo reduction
• Supports both ground start and loop start configurations with programmable line interface parameters
• Includes parallel handset detection and polarity reversal detection capabilities

Telecom Applications

• DSL Integrated Access Devices (IADs)
• VoIP gateways
• PBX and IP-PBX systems
• Voice mail systems
• DECT base stations

Telecom Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the component meets the required ambient operating temperature range for the intended application environment.

Telecom Selection Notes

Select this model when a system-side voice DAA solution is required for FXO applications. It must be paired with a compatible line-side device such as the Si3011, Si3018, or Si3019. Verify that the target application requires the extended industrial temperature range (-40°C to +85°C) provided by the G-grade designation.

Telecom Part Context

This component belongs to the Si3050 series of programmable voice DAA solutions from Skyworks Solutions. It functions as the system-side processor in a two-device architecture, communicating with a line-side device via an isolation barrier. The series is designed to replace traditional transformer-based designs with a compact, software-configurable alternative.
