SI3008-A-FS

Overview

The Si3008-A-FS is an 8-pin SOIC line-side Device Access Arrangement (DAA) component within the Silicon Labs Si2493 chipset family. It serves as a low-voltage modem device designed to connect directly with the telephone local loop, specifically interfacing with TIP and RING lines. This hardware-based solution integrates with host processors via serial or parallel interfaces, supporting various modulation types including PCM, TCM, QAM, FSK, and DPSK. The DAA provides necessary isolation and signal conditioning for analog telephony applications.

Feature Summary

• Direct connection capability to telephone local loop TIP and RING lines
• Integration as part of a complete controller-based modem solution
• Support for multiple modulation standards including PCM, TCM, QAM, FSK, and DPSK

Applications

• Hardware-based modem designs requiring direct line-side connectivity
• Low-voltage telephony interface circuits
• Digital subscriber line access multiplexers (DSLAM) front-ends

Procurement Notes

Verify the specific suffix 'A-FS' against official Silabs documentation to confirm package type and temperature grade. Ensure compatibility with the Si2493 controller chip in system design. Check for RoHS compliance status in current datasheets. Confirm availability through authorized distributors only.

Selection Notes

Select this component when designing a modem solution requiring direct analog line interface. It pairs with the Si2493 controller. Consider the 8-pin SOIC package constraints. Verify voltage levels match the target application's power supply. Ensure the required modulation types are supported by the paired controller.

Part Context

The Si3008 is a line-side DAA device belonging to the Si2493 chipset family. It works in conjunction with the Si2493 modem controller to form a complete hardware modem solution. The family supports various interfaces including serial, parallel, PCM, and EEPROM options depending on the controller package.

Replacement Considerations

Consult official Silabs documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics before substitution. Ensure the replacement maintains compatibility with the Si2493 controller interface.
