SI3016-F-FSR

Overview

The SI3016-F-FSR is a line-side Direct Access Arrangement (DAA) integrated circuit manufactured by Silicon Laboratories. It provides a programmable telephone line interface compliant with global regulatory standards, including FCC and CTR21. The device integrates an analog front end, hybrid, ring detector, and isolation barrier within a 16-pin SOIC package. It operates on a 3.3 V or 5 V supply and interfaces directly to system-side processors. Key electrical parameters include up to 5000 V isolation, 84 dB dynamic range, and transmit/receive levels of -1 dBm or +3.2 dBm.

Feature Summary

• Integrated direct access arrangement eliminating discrete analog front ends and isolation transformers
• Programmable line interface supporting multiple global DC and AC termination modes
• Proprietary capacitive isolation technology for high-voltage safety compliance
• Built-in support for caller ID, pulse dialing, and billing tone detection

Applications

• V.90 modems
• Voice mail systems
• Fax machines
• VOIP systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with the host processor's integrated DAA system-side module before integration. Check for RoHS compliance status in official documentation.

Selection Notes

Select this component for single-channel telephone line interface designs requiring global regulatory compliance. Verify that the host system supports the required serial communication protocol for register configuration. Confirm power supply voltage requirements match the 3.3 V or 5 V operational specifications.

Part Context

This part belongs to the Si3016 family of enhanced global direct access arrangements. It is designed to work in conjunction with Silicon Laboratories' integrated DAA system-side interface devices. The F-FSR suffix typically denotes specific packaging or reel configurations within the standard SOIC-16 form factor.

Replacement Considerations

Direct replacements may include other Si3016 variants with different suffixes such as BS or FS, provided the pinout and functional specifications remain identical. Verify isolation voltage ratings and regulatory certifications when substituting.
