SI2493-D-FTR

Overview

The SI2493-D-FTR is a Global Direct Access Arrangement (DAA) integrated circuit manufactured by Skyworks Solutions Inc. under the ISOmodem series. It supports V.21, V.22, V.23, V.29, V.32, V.34, V.90, V.92, Bell 103, and Bell 212A data formats. The device operates on a supply voltage of 3V to 3.6V and utilizes a 24-TSSOP package with a width of 4.40mm. It functions as a system-side modem interface.

Feature Summary

• Supports comprehensive global telephony standards including V-series and Bell protocols
• Integrates Direct Access Arrangement (DAA) functionality for telecom interfaces
• Designed for surface mount installation in compact electronic systems

Applications

• System-side modem implementations
• Telecommunications equipment requiring global DAA compliance
• Data communication interfaces supporting legacy and standard protocols

Procurement Notes

Verify the specific suffix -FTR against official Skyworks documentation to confirm tape and reel packaging requirements. Ensure compatibility with the 24-TSSOP footprint during PCB layout. Confirm that the component meets the required moisture sensitivity level (MSL 3) handling procedures before assembly.

Selection Notes

Select this component when a system-side solution is required rather than a client-side DAA. Compare the SI2493-D-GTR if tube packaging is preferred over tape and reel. Verify that the 3V to 3.6V operating range aligns with the target system power supply design constraints.

Part Context

This part belongs to the SI2493 family of ISOmodem products from Skyworks Solutions. It serves as the system-side counterpart to client-side DAAs, facilitating connection to public switched telephone networks. The family includes variants like the SI2493-D-GT and SI2493-D-GTR which differ primarily in packaging configuration.

Replacement Considerations

The SI2493-D-GTR is a functionally equivalent alternative offering the same specifications in tube packaging instead of tape and reel. Designers should verify pinout compatibility and thermal characteristics before substituting.
