SI3056-D-FSR

Telecom Overview

The Si3056-D-FSR is a global serial interface direct access arrangement (DAA) manufactured by Skyworks Solutions Inc. It operates on a 3.3 V digital supply voltage with a typical current consumption of 15 mA. The device supports an ambient operating temperature range from 0 °C to 70 °C and utilizes a 16-pin SOIC package. It provides over 5000 V isolation through proprietary technology, eliminating the need for external analog front ends, isolation transformers, relays, opto-isolators, and 2- to 4-wire hybrids.

Telecom Feature Summary

• Integrates programmable line interface, codec, and hybrid functions
• Supports Type I and II caller ID and parallel handset detection
• Features integrated ring detector and overload protection

Telecom Applications

• V.92 modems
• Voice mail systems
• Multi-function printers
• Set-top boxes
• Fax machines

Telecom Procurement Notes

Verify component authenticity using official Skyworks documentation and manufacturer markings. Confirm the specific suffix matches the required packaging configuration. Ensure compliance with RoHS standards and check for any product change notifications regarding lead frame modifications or moisture sensitivity ratings before procurement.

Telecom Selection Notes

Select this component when designing global telephone line interfaces requiring reduced discrete component counts. It directly interfaces with standard modem DSPs via a serial control interface. Verify that the application environment remains within the specified 0 °C to 70 °C operating temperature range and requires a 3.3 V power supply.

Telecom Part Context

This part belongs to the Si3056 family of global DAAs. It is designed to replace traditional discrete DAA solutions by integrating necessary isolation and signal conditioning into a single low-profile package. The device simplifies design complexity while maintaining compliance with international regulatory requirements for telephone networks.

Telecom Replacement Considerations

SI3050-E1-FTR is listed as a manufacturer-recommended alternative.
