SI2494-A-FMR

Overview

The SI2494-A-FMR is a system-side ISOModem network controller and processor IC manufactured by Skyworks Solutions. It supports V.92 data protocols with a maximum data rate of 56 kb/s. The device operates on a single 3.3 V power supply, drawing 17 mA during operation, with an acceptable voltage range between 3 V and 3.6 V. Communication interfaces include SPI and UART. The component is housed in a QFN-38 package designed for surface mount technology. It functions within an industrial temperature range from -40°C to +85°C and utilizes a 4.92 MHz clock frequency.

Feature Summary

• Supports V.92 data protocol standards for system-side modem applications
• Integrates SPI and UART communication interfaces for host connectivity
• Operates at 56 kb/s data transmission rates

Applications

• System-side ISOModem implementations
• Network controller processor designs requiring V.92 compliance
• Industrial communication equipment operating in extended temperature ranges

Procurement Notes

Verify the specific suffix 'FMR' against official Skyworks documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with the QFN-38 footprint and check moisture sensitivity levels before assembly. Confirm that the -40°C to +85°C operating range meets the target application's environmental requirements.

Selection Notes

Select this component when a system-side modem solution is required with V.92 support. Compare the QFN-38 package against available alternatives like the SI2494-A-FM or SI2494-A-GM based on specific temperature grades and packaging preferences. Verify interface compatibility with the host microcontroller.

Part Context

This part belongs to the SI2494 series of ISOModems from Skyworks Solutions. The series includes variants such as SI2494-A-FM and SI2494-A-GM, which share similar core functionalities but may differ in temperature ratings or packaging formats. The SI2494 series is designed for robust network controller applications.

Replacement Considerations

The SI2494-A-FM and SI2494-A-GM are related parts within the same family. Verify if the temperature range or packaging differences between these variants affect the design. No other direct substitute part numbers are confirmed in public documentation.
