SI2493-D-FSR

Overview

The SI2493-D-FSR is a network controller and processor IC belonging to the ISOmodem series, manufactured by Skyworks Solutions Inc. It functions as a system-side modem supporting data rates up to 56 kb/s with an operating frequency of 4.92 MHz. The device interfaces via SPI and UART protocols and operates on a supply voltage ranging from 3 V to 3.6 V, drawing a typical current of 17 mA. It is housed in a 24-TSSOP package suitable for surface mount installation and supports data formats including V.21, V.22, V.23, V.29, V.32, V.34, V.90, V.92, Bell 103, and Bell 212A.

Feature Summary

• Supports comprehensive legacy modem protocols including V-series and Bell standards for global compatibility.

Applications

• System-side telecommunications equipment requiring integrated modem functionality.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly. Ensure storage conditions adhere to humidity control requirements to prevent damage before reflow soldering.

Selection Notes

Select this model for applications requiring a complete system-side modem solution with standard serial interfaces. Verify that the host system provides adequate power within the 3 V to 3.6 V range and supports the required SPI or UART communication protocols for proper integration.

Part Context

This component is part of the broader SI2493 family of ISOmodems designed for telecommunications networking. It serves as a specialized network controller and processor IC, distinct from evaluation boards like the SI2493FT18-EVB or companion DAA chips such as the SI3018.

Replacement Considerations
