SI32391-B-FM

Telecom Overview

The SI32391-B-FM is a single-channel ProSLIC analog interface integrated circuit designed for telecommunications applications. It operates within a supply voltage range of 3.15 V to 3.45 V and supports an operating temperature range from -40 °C to +85 °C. The device is housed in a QFN-48 surface-mount package. It functions as a subscriber line interface concept (SLIC) IC, providing the necessary analog front-end processing for telephone lines.

Telecom Feature Summary

• Integrates subscriber line interface concept (SLIC) functionality with codec capabilities
• Supports standard analog telephony interfaces
• Designed for robust operation across industrial temperature ranges

Telecom Applications

• Analog telephone line interface circuits
• Telecommunications equipment requiring single-channel SLIC
• VoIP gateways and analog adapters

Telecom Procurement Notes

Verify the specific suffix FM against official Skyworks documentation to confirm pinout and packaging details. Ensure compatibility with existing board layouts referencing the QFN-48 footprint. Confirm that the 3.3V nominal supply aligns with system power rails before integration.

Telecom Selection Notes

Select this component when a single-channel analog interface with integrated codec is required. Compare against other ProSLIC variants if multiple channels or different packaging options are needed. Verify thermal performance requirements given the QFN-48 package constraints.

Telecom Part Context

This part belongs to the SI32391 series of ProSLIC devices from Skyworks Solutions. It represents a specialized solution for analog telephony interfaces, distinct from clock generators or RF components offered by the same manufacturer.

Telecom Replacement Considerations

Direct substitutes may include other SKUs within the SI32391 family with differing suffixes. Verify functional equivalence and pin compatibility before substitution.
