SI3216M-C-FM

Telecom Overview

The SI3216M-C-FM is a ProSLIC subscriber line interface concept (SLIC) integrated circuit manufactured by Skyworks Solutions Inc. It provides one channel of FXS functionality 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, consuming 44.7 mA of working power current. It features a QFN-38 package for surface mount installation and functions across a temperature range of 0°C to +70°C.

Telecom Feature Summary

• Integrates ProSLIC technology for single-channel FXS subscriber line interfacing
• Supports ISI interface connectivity for digital telephony applications
• Includes integrated CODEC functionality for voice signal processing

Telecom Applications

• Digital subscriber line access multiplexer (DSLAM) systems
• Integrated voice response units (IVR)
• Telecom gateway equipment

Telecom Procurement Notes

Verify the specific suffix 'FM' against official Skyworks documentation to confirm the exact package variant and tape/reel specifications. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the procurement source provides valid traceability for this telecom interface IC. Check for any moisture sensitivity level (MSL) handling restrictions during storage and assembly processes.

Telecom Selection Notes

Select this component when designing systems requiring a single-channel FXS SLIC with ISI interface compatibility. It is suitable for applications needing integrated CODEC capabilities within a compact QFN-38 footprint. Consider the 0°C to +70°C operating temperature range for environmental constraints. Evaluate the 3.13 V to 3.47 V supply voltage requirements against system power rails.

Telecom Part Context

This part belongs to the Skyworks ProSLIC family of subscriber line interface circuits. These devices are designed to replace traditional discrete analog front-end components in telecommunications hardware. The SI3216M-C-FM specifically targets high-volume consumer and enterprise telecom equipment requiring simplified board space and reduced bill-of-materials complexity.

Telecom Replacement Considerations

Direct substitutes include other variants within the SI3216M series or related ProSLIC families such as the SI3217x series, provided they match the required channel count and interface type. Verify pin-to-pin compatibility and software register compatibility before substitution.
