SI3200-FS

Telecom Overview

The SI3200-FS is a single-channel analog front-end integrated circuit designed for telephony applications, manufactured by Skyworks Solutions Inc. It integrates a Subscriber Line Interface Circuit (SLIC) and a CODEC within a single package. The device operates from a 3.3V supply and supports standard telephony line feed voltages up to 100V. It utilizes a 16-pin SOIC surface-mount package with a maximum operating temperature of 70°C. The component includes internal protection features and meets RoHS compliance standards for environmental safety.

Telecom Feature Summary

• Integrates SLIC and CODEC functions in a single channel
• Supports high voltage line feed requirements
• Operates on low voltage digital supplies
• Includes built-in line protection mechanisms

Telecom Applications

• POTS telephone systems
• VoIP gateways
• Telecom interface cards

Telecom Procurement Notes

Verify the manufacturer designation carefully, as Skyworks acquired Silicon Laboratories' telecom portfolio. Confirm the specific suffix matches the required revision level. Check for end-of-life notices or obsolescence status before finalizing procurement plans. Ensure the package type aligns with existing PCB footprints.

Telecom Selection Notes

Select this component for single-line telephony interfaces requiring integrated analog and digital processing. Compare pin compatibility with legacy designs if replacing older silicon laboratory parts. Verify that the 16-pin SOIC footprint fits the mechanical constraints. Ensure the system design accommodates the 3.3V logic levels and 100V line interface requirements.

Telecom Part Context

This part belongs to the ProSLIC family of subscriber line interface circuits. It serves as a direct replacement for previous generations of standalone SLIC and CODEC combinations. The integration reduces board space and simplifies bill of materials for modern telephony equipment manufacturers.

Telecom Replacement Considerations

Check for SI3200-G-FS or SI3200-D-FS variants for potential pin-compatible upgrades. Verify functional equivalence with SI3205 series devices if multi-channel solutions are needed.
