SI2493-C-FTR

Overview

The SI2493-C-FTR is a system-side Data Access Arrangement (DAA) modem integrated circuit manufactured by Skyworks Solutions Inc. It belongs to the ISOmodem series and supports global telephony standards including V.21, V.22, V.23, V.29, V.32, V.34, V.90, V.92, Bell 103, and Bell 212A. The device operates on a supply voltage range of 3V to 3.6V and is housed in a 24-TSSOP package with a width of 4.40mm. It utilizes SPI and UART interfaces for communication. The component has a maximum data rate of 56 kb/s and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports comprehensive global modem protocols for international telecommunications compatibility
• Integrates Data Access Arrangement (DAA) functionality for direct line connection
• Provides flexible interface options via SPI and UART connections

Applications

• Global telephone modems requiring multi-standard protocol support
• Data Access Arrangement (DAA) implementations in telecom equipment
• System-side modem integration for network controllers

Procurement Notes

Verify the specific suffix 'C' against official Skyworks documentation to confirm exact electrical characteristics and pinout compatibility. Confirm current production status as some variants in this family have been marked obsolete or not recommended for new designs. Ensure the tape and reel packaging matches the required manufacturing process specifications.

Selection Notes

Select this component when designing systems requiring a single-chip solution for multiple global modem standards. Compare the 24-TSSOP package constraints against available board space. Verify that the 3V to 3.6V supply voltage aligns with the target system's power architecture and that the -40°C to +85°C industrial temperature range meets environmental requirements.

Part Context

This part is a variant within the Skyworks ISOmodem family, specifically designed for system-side applications. It shares the core architecture with other SI2493 derivatives but differs in packaging and potentially minor electrical parameters defined by the suffix. It serves as a key component for enabling global connectivity in legacy and specialized modem hardware.

Replacement Considerations

Official substitutes include SI2493-D-GT and SI2493-D-GTR. Verify pin-to-pin compatibility and parameter alignment before substitution. Note that some family members may be obsolete; check current availability and design-in status.
