SI3019-F-GTR

Telecom Overview

The SI3019-F-GTR 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 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 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 voice processing
• Patented isolation technology providing over 5000 V isolation
• Programmable digital gain in 0.1 dB increments
• Supports Type I and II caller ID and pulse dialing

Telecom Applications

• Voice DAA line-side solutions
• Telecom interface systems requiring high isolation

Telecom Procurement Notes

Verify the specific suffix 'GTR' against official Skyworks documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS compliance requirements as indicated in general product descriptions. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times.

Telecom Selection Notes

Select this component for applications requiring integrated voice DAA functionality with high voltage isolation. Consider the 3.3 V supply constraint and the need for SPI or GCI control interfaces. Evaluate the 80 dB dynamic range and programmable gain features against system audio quality requirements. Verify that the device supports the required loop start or ground start configurations.
