SI3018-F-GSR

Telecom Overview

The Skyworks SI3018-F-GSR is a Direct Access Arrangement (DAA) line-side device designed for global telephone line compliance. It operates with a 3.0 V to 3.6 V digital supply voltage and supports an operating temperature range of 0°C to 70°C. The component features a 16-SOIC package and interfaces via parallel, SPI, or UART protocols. Key electrical parameters include a typical power supply current of 15 mA and a dynamic range of 80 dB in transmit/receive paths. It provides DC termination voltages up to 9 V and ring detect thresholds ranging from 13.5 V to 23.65 V rms.

Telecom Feature Summary

• Integrated codec and hybrid circuitry that eliminates the need for discrete analog front ends, isolation transformers, relays, opto-isolators, and external 2- to 4-wire hybrids.
• Programmable line interface supporting AC and DC termination, ringer impedance adjustment, and polarity reversal detection.
• Supports Type I and II caller ID, pulse dialing, and parallel handset detection with integrated overload protection.

Telecom Applications

• V.92 modems
• Voice mail systems
• Multi-function printers
• Set-top boxes
• Fax machines

Telecom Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm packaging details. Ensure the component meets RoHS3 standards and check for any recent Product Change Notices regarding assembly sources or labeling updates before finalizing procurement orders.

Telecom Selection Notes

Select this component when designing systems requiring a complete DAA solution without discrete AFE components. Verify compatibility with standard modem DSPs and ensure the serial interface configuration matches the host controller's master or slave requirements.

Telecom Part Context

The SI3018 is part of the Si3018/19/10 family, which serves as the line-side interface for the Si3056 Global Serial Interface DAA system. This family enables direct connection to DSPs while maintaining regulatory compliance through proprietary isolation technology.
