SI3019-F-GM

Telecom Overview

The SI3019-F-GM is a programmable voice Direct Access Arrangement (DAA) manufactured by Skyworks Solutions Inc. It integrates a codec and a 2- to 4-wire analog hybrid for telephone line interface applications. The device supports PCM highway data interfaces with μ-law/A-law companding and offers an SPI or GCI control interface. Key electrical specifications include an 80 dB dynamic range for both transmit and receive paths, a +6 dBm or +3.2 dBm TX/RX level mode, and a 3.3 V power supply requirement. It features integrated ring detection, caller ID support, and polarity reversal detection. The component provides greater than 5000 V isolation using patented technology and supports daisy-chaining for up to 16 devices.

Telecom Feature Summary

• Integrated codec and analog hybrid for 2- to 4-wire conversion
• Patented isolation technology exceeding 5000 V
• Programmable digital gain in 0.1 dB increments
• Supports pulse dialing and Type I/II caller ID

Telecom Applications

• Telephone line interface circuits
• Voice DAA solutions
• Telecom equipment requiring high isolation

Telecom Procurement Notes

Verify the specific suffix 'GM' against official Skyworks documentation to confirm package type and tape/reel specifications. Ensure compliance requirements such as RoHS status are confirmed via the latest datasheet revision. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.

Telecom Selection Notes

Select this component when a fully integrated voice DAA with high isolation is required. Consider the 3.3 V supply voltage and PCM/GCI interface compatibility with the host system. Evaluate the need for daisy-chaining capabilities if multiple lines are managed. Verify that the programmable line interface parameters match the target network standards.

Telecom Part Context

The SI3019 belongs to Skyworks' family of programmable voice DAA solutions. It is designed to replace discrete DAA implementations by integrating line interface, hybrid, and codec functions. The device is suitable for global telephony applications due to its programmable termination and ring detect thresholds.

Telecom Replacement Considerations

Check Skyworks documentation for direct pin-to-pin replacements or upgraded variants within the SI3019 series. Verify functional equivalence regarding isolation voltage and interface protocols before substituting.
