SI3018-FS

Telecom Overview

The SI3018-FS is a Direct Access Arrangement (DAA) integrated circuit manufactured by Skyworks Solutions Inc. Designed for telecommunications applications, this single-channel device operates within a supply voltage range of 3V to 3.6V and consumes 8.5mA of supply current. It supports parallel, SPI, and UART interfaces for system control. The component is housed in a 16-SOIC package with a width of 3.90mm and functions reliably across an operating temperature range of 0°C to 70°C. It holds a Moisture Sensitivity Level (MSL) rating of 3, corresponding to 168 hours of reflow soldering capability.

• Industrial communication devices

Telecom Procurement Notes

Verify the specific suffix against official Skyworks documentation to confirm exact packaging and tape-and-reel specifications. Ensure compliance with RoHS3 standards and check MSL handling requirements during assembly. Confirm availability status as distribution channels may vary.

Telecom Selection Notes

Select this component when a single-channel DAA solution with flexible digital interface options is required. Consider the 16-SOIC footprint for PCB layout constraints. Verify that the 3V to 3.6V supply range matches the target system design before finalizing the bill of materials.

Telecom Part Context

This part belongs to the broader family of telecom interface ICs from Skyworks. It serves as a line-side interface component often paired with modems or ISDN controllers. The SI3018 series provides essential analog front-end capabilities for connecting digital systems to telephone networks.

Telecom Replacement Considerations

Check for SI3018 variants with different suffixes such as -F-FSR or -FS-R which may offer identical electrical performance but differ in reel packaging quantities or moisture sensitivity labeling.
