SI3016-FS

Overview

The SI3016-FS is a line-side Device Access Arrangement (DAA) manufactured by Texas Instruments. It is designed for use with the TMS320C54V90 digital signal processor to provide modem connectivity. The component integrates telephony interface functions, supporting operation with 3.3 V and 5 V I/O voltages while maintaining a 1.5 V core supply. It operates within an industrial temperature range of 0°C to +100°C and is housed in a tube package.

Feature Summary

• Integrates line-side DAA functionality specifically for embedded DSP modem solutions
• Supports mixed voltage interfaces with 3.3 V and 5 V I/O capabilities
• Designed for direct integration with C5000 series processors

Applications

• Embedded V90 modem solutions
• Digital signal processor-based telephony systems
• Line-side device processor integrated circuits

Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited supply constraints. Confirm RoHS compliance details directly with the manufacturer or authorized distributors, as regulatory status can vary by production batch. Ensure the specific suffix matches design requirements before ordering.

Selection Notes

Select this component when designing modems requiring a dedicated line-side interface for the TMS320C54V90 DSP. Verify that the system architecture supports the required 1.5 V core voltage alongside the necessary 3.3 V or 5 V I/O levels. Ensure the thermal environment remains within the specified 0°C to +100°C operating range for reliable performance.

Part Context

This part belongs to the TMS320C54V90 series ecosystem, serving as a companion peripheral to the C5000 family DSPs. It addresses the specific need for integrated telephony interface management in embedded processing applications, distinguishing it from general-purpose analog comparators or standalone data converters found in other TI product lines.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Texas Instruments resources for legacy replacement strategies or pin-compatible alternatives if this component is no longer in active production.
