SI3015-KS

Overview

The SI3015-KS is a Direct Access Arrangement (DAA) integrated circuit designed for use with the Si2400 ISOmodem chipset. It provides a globally compliant line interface to meet international telephone network requirements. The component features capacitive isolation, parallel phone detection, and overcurrent protection. It supports operating supply voltages of 3.0 V to 5.25 V and operates within temperature ranges of 0°C to 70°C (K-Grade) or -40°C to 85°C (B-Grade). The device utilizes a 16-pin Small Outline Integrated Circuit (SOIC) package.

Feature Summary

• Integrated capacitive isolation technology for safety compliance
• Programmable global line interface supporting multiple termination standards
• Built-in parallel handset detection and overcurrent monitoring capabilities

Applications

• Set Top Boxes
• Power Meters
• Security Systems
• ATM Terminals
• Medical Monitoring
• Point-of-Sale terminals

Procurement Notes

Verify the specific grade suffix (KS) against manufacturer documentation to confirm temperature range and performance specifications. Ensure compatibility with the paired Si2400 modem controller in system designs. Confirm RoHS compliance status through official datasheets prior to integration.

Selection Notes

Select this component when designing embedded modem applications requiring a compact footprint and low power consumption. It serves as the analog front-end interface for the Si2400 digital modem processor. Verify that the application environment matches the specified operating temperature limits for the K-Grade variant.

Part Context

The SI3015 functions as the companion DAA chip to the Silicon Laboratories Si2400 ISOmodem. Together, they form a complete modem solution that eliminates the need for separate DSP data pumps, analog front ends, isolation transformers, and voice codecs. This pairing simplifies board space requirements and reduces overall system complexity.
