SI3010-KS

Telecom Overview

The Si3010-KS is a line-side component within the Silicon Labs Si3056 Global Serial Interface Direct Access Arrangement (DAA) system. It operates with a 3.3 V digital supply voltage and supports sample rates up to 16 kHz. The device provides over 5000 V isolation using proprietary technology, eliminating the need for external analog front ends or isolation transformers. It features an integrated codec, 2- to 4-wire hybrid, and ring detector. Key electrical parameters include a typical dynamic range of approximately 70 dB when paired with the Si3056 controller, transmit full-scale levels configurable from 0 dBm to +6.0 dBm, and support for Type I/II caller ID.

Telecom Feature Summary

• Integrated direct access arrangement (DAA) functionality that replaces discrete analog front ends, isolation transformers, relays, opto-isolators, and hybrids.
• Proprietary isolation technology providing greater than 5000 V isolation barrier between line side and digital side.
• Supports global telephone line interface requirements including AC/DC termination, ring detection, and polarity reversal.
• Enables direct connection to standard modem DSPs via serial interface control.

Telecom Applications

• V.92 modems
• Voice mail systems
• Multi-function printers
• Set-top boxes
• Fax machines

Telecom Procurement Notes

Verify the specific ordering suffix KS against the manufacturer's current datasheet revision to confirm package type and temperature grade. Ensure compatibility with the Si3056 system-side controller for proper initialization and register configuration. Confirm RoHS compliance status if required by local regulations.

Telecom Selection Notes

Select the Si3010-KS when designing globally compliant DAA solutions requiring high integration. This component pairs specifically with the Si3056 controller. Consider the reduced bill of materials compared to legacy Si3034/35/44 designs. Verify that the target application requires the specific line-side characteristics provided by the Si3010 variant rather than the enhanced Si3018 or Si3019 options.

Telecom Part Context

The Si3010-KS belongs to the Si3056 family of programmable voice DAAs. It functions as the line-side interface for the Si3056 system-side controller. This family eliminates traditional discrete components to reduce cost and board space while maintaining regulatory compliance for global telephony applications.

Telecom Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Legacy upgrades from Si3034/35/44 require design changes due to pinout incompatibility.
