SI2418-A-FT

Overview

The SI2418-A-FT is a system-side modem integrated circuit manufactured by Skyworks Solutions Inc. It belongs to the ISOmodem product family and supports V.34 data transmission protocols with a maximum baud rate of 56 kbps. The device is designed for telecommunications applications requiring reliable analog-to-digital interface capabilities. It is housed in a 24-TSSOP surface-mount package with a width of 4.40 mm. The component exhibits moisture sensitivity level (MSL) 3, corresponding to a reflow duration of 168 hours under JEDEC standards. Its export classification is EAR99.

Feature Summary

• Supports V.34 modulation format for high-speed data communication
• Integrates Analog-to-Digital Acquisition Arrangement (DAA) functionality
• Designed for system-side deployment in telecommunication networks

Applications

• Telecommunications infrastructure systems
• System-side modem implementations
• Data acquisition arrangements

Procurement Notes

Verify the current design status before procurement, as this component may be marked as not recommended for new designs due to potential minimum order quantity restrictions or limited availability. Confirm the specific ordering suffix matches the required package configuration. Ensure compliance with moisture sensitivity handling procedures during assembly to maintain component integrity.

Selection Notes

Select this component when a dedicated system-side modem solution supporting V.34 protocols is required. Verify compatibility with existing DAA requirements and ensure the 24-TSSOP footprint fits the target PCB layout. Consider lifecycle status and long-term supply stability compared to newer alternatives within the ISOmodem portfolio.

Part Context

This part is a member of the Skyworks ISOmodem series, which provides integrated solutions for legacy and specialized telecommunication modem applications. The SI2418 variant specifically targets system-side integration, distinguishing it from user-side modems. It complements other components like the SI2415 evaluation boards within the broader ecosystem of telecom interface devices offered by the manufacturer.

Replacement Considerations

The SI2435-F-FT is identified as a manufacturer-recommended alternative. Verify functional equivalence and pinout compatibility before substitution. Check if the replacement addresses any obsolescence concerns while maintaining support for the required V.34 protocol specifications.
