AFE1144E

Analog Front End (AFE) Overview

The AFE1144E is a single-channel analog front-end (AFE) designed for HDSL and MDSL applications. It integrates a 14-bit digital subscriber line interface circuit (SLIC). The device operates with a 5V analog supply and supports digital supplies ranging from 3.3V to 5V. It features a surface-mountable 28-pin SSOP package. The component has a power rating of 250 mW and functions within an operating temperature range of -40°C to +85°C.

Analog Front End (AFE) Feature Summary

• Integrates a 14-bit digital SLIC for HDSL/MDSL analog front-end processing
• Supports dual voltage operation with 5V analog and 3.3V-5V digital supplies
• Designed for surface-mount assembly in compact 28-SSOP packages

Analog Front End (AFE) Applications

• HDSL analog front-end systems
• MDSL analog front-end systems
• Digital subscriber line interface circuits

Analog Front End (AFE) Procurement Notes

Verify product status as the AFE1144E is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers, as direct new production may not be guaranteed. Ensure compatibility with existing system designs requiring this specific legacy component.

Analog Front End (AFE) Selection Notes

Select this component for applications requiring a dedicated 14-bit digital SLIC for HDSL or MDSL interfaces. Consider the 28-SSOP package constraints and the specific 5V analog supply requirement. Evaluate thermal management needs given the 250 mW power rating and industrial temperature range specifications.

Analog Front End (AFE) Part Context

Burr-Brown was acquired by Texas Instruments in 2000. The AFE1144E belongs to the family of high-performance analog front-end solutions originally developed by Burr-Brown for telecommunications applications. This part represents legacy technology integrated into TI's broader portfolio after the acquisition.

Analog Front End (AFE) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the AFE1144E is marked obsolete, alternative components must be evaluated based on functional equivalence for HDSL/MDSL SLIC requirements rather than direct cross-reference data.
