SI3210M-E-FMR

Telecom Overview

The SI3210M-E-FMR is a Pro Subscriber Line Interface Concept (SLIC) integrated circuit manufactured by Skyworks Solutions Inc. It provides a single channel for FXS applications with an ISI interface and supports -100 V operation. The device operates within a supply voltage range of 3.13 V to 3.47 V, drawing a typical operating current of 44.7 mA. It is housed in a QFN-38 package suitable for surface mount installation. The component functions across a temperature range from -40°C to +85°C and features a 3-wire interface type.

Telecom Feature Summary

• Integrates Pro SLIC technology for subscriber line interface concepts
• Supports FXS application requirements with ISI interface capability
• Designed for robust operation with -100 V support

Telecom Applications

• FXS subscriber line interface circuits
• Telecom interface systems requiring ISI connectivity
• Voice gateway hardware implementations

Telecom Procurement Notes

Verify the specific suffix 'E' against official Skyworks documentation to confirm the extended industrial temperature rating (-40°C to +85°C). Ensure the QFN-38 package variant matches design constraints. Confirm that the ISI interface requirement aligns with system architecture before procurement. Cross-reference the manufacturer part number with authorized distributors to ensure genuine components.

Telecom Selection Notes

Select this component when a single-channel FXS solution with ISI interface is required. The QFN-38 package offers a compact footprint for dense PCB layouts. Consider the -40°C to +85°C operating range for industrial or outdoor deployments. Verify power consumption requirements against the 44.7 mA typical current draw. Ensure compatibility with the 3.13 V to 3.47 V supply voltage range.

Telecom Part Context

This part belongs to the Skyworks SLIC family, designed for telecom interface applications. It complements other models like the SI32192 series but differs in interface type and package configuration. The SI3210M-E-FMR specifically targets FXS applications using the ISI interface, distinguishing it from PCM-based alternatives. It represents a specialized analog semiconductor solution for connecting voice endpoints.
