SI3019-F-GT

Telecom Overview

The SI3019-F-GT 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 telephony applications. The device supports PCM highway data interfaces with μ-law/A-law companding and features an SPI control interface alongside GCI support. Key electrical parameters 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 provides greater than 5000 V isolation using patented technology and supports daisy-chaining for up to 16 devices.

Telecom Feature Summary

• Integrated codec and 2- to 4-wire analog hybrid for signal processing
• Patented isolation technology providing high voltage safety
• Programmable digital hybrid for near-end echo reduction
• Support for Type I and II caller ID and pulse dialing

Telecom Applications

• Global voice DAA line-side implementations
• Telecom interface systems requiring high isolation
• Programmable telephone handsets and base stations

Telecom Procurement Notes

Verify the specific suffix against official Skyworks documentation to confirm package type and temperature grade. Ensure the component matches the required isolation standards and interface protocols for the target design. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status.

Telecom Selection Notes

Select this component when a fully integrated voice DAA solution is required with high isolation capabilities. Consider the 3.3 V supply constraint and the need for programmable gain and hybrid settings. Evaluate the daisy-chain capability if multiple units are needed in a single system architecture.

Telecom Part Context

The SI3019 belongs to Skyworks' family of programmable voice DAA solutions. It is designed to replace discrete DAA designs by integrating necessary analog and digital functions into a single IC. This simplifies board layout and reduces component count for telecom equipment manufacturers.

Telecom Replacement Considerations

Check for pin-compatible alternatives within the SI301x series. Verify that any substitute maintains the same isolation rating and interface compatibility.
