SI32284-A-ZM2R

Telecom Overview

The Si32284-A-ZM2R is a wideband dual FXS ProSLIC device from the Si3228x series, designed for customer-specific applications. It integrates two complete foreign exchange station interfaces within a single 7x7 mm 48-pin QFN package. The component operates on a 3.3 V supply and supports ISI digital interfaces. Key electrical parameters include a maximum battery voltage of -106 V and an operating temperature range of 0 to 70 °C. It features Smart Ringing technology to reduce peak current requirements.

Telecom Feature Summary

• Integrates two complete FXS channels with all BORSCHT functions in a compact 48-pin QFN package
• Supports wideband audio for enhanced voice quality and includes Smart Ringing to lower peak current demands
• Incorporates programmable DC-DC controller supporting low-cost capacitive boost configurations
• Provides flexible configuration via software-programmable parameters for impedance, loop feed, and ringing

Telecom Applications

• VoIP gateways and routers
• Analog Terminal Adapters (ATA)
• Private Branch Exchange (PBX) systems
• Wireless Fixed Terminals (WFT)

Telecom Procurement Notes

Verify the specific customer designation associated with the ZM2 suffix directly with Skyworks Solutions prior to procurement. Confirm that the ISI interface requirement aligns with the host system design. Ensure the commercial temperature grade meets the operational environment constraints. Validate the 48-pin QFN land pattern against PCB layout guidelines.

Telecom Selection Notes

Select this part when a dual-channel FXS solution with ISI interface and Smart Ringing is required. The ZM2 suffix indicates a customer-specific variant; standard equivalents like Si32284-A-FM or Si32284-A-GM may be considered if custom specifications are not mandatory. Ensure the application utilizes a 3.3 V logic level and supports the necessary ISI timing constraints.

Telecom Part Context

This component belongs to the Si3228x family of ProSLIC devices, which provide integrated SLIC, codec, and DTMF functions. The Si32284 variant specifically targets applications requiring Smart Ringing and ISI connectivity. The ZM2 suffix denotes a specialized customer-specific version within the commercial temperature grade lineup.

Telecom Replacement Considerations

Si32284-A-FM provides identical functionality in a standard commercial package. Si32284-A-GM offers the same features with an extended industrial temperature range. Standard versions should be verified for compatibility if the customer-specific ZM2 parameters are not strictly required.
