SI32193-A-ZM2

Telecom Overview

The Si32193-A-ZM2 is a single-channel Foreign Exchange Station (FXS) telephony interface solution from the ProSLIC family. It integrates all BORSCHT functions, including SLIC, CODEC, and DTMF detection, within a 4 x 6 mm, 38-pin QFN package. The device operates from a 3.3 V supply with a 3-wire ISI digital interface supporting 1.8 to 3.3 V I/O. It features wideband audio support (150 Hz–6.8 kHz), a programmable DC-DC controller for capacitive boost configurations, and supports battery voltages up to -100 V. The operating temperature range is 0 to 70 °C.

Telecom Feature Summary

• Integrates complete FXS functionality including BORSCHT, CODEC, and DTMF detection in a compact package
• Supports wideband audio for enhanced voice quality and includes built-in DSP for diagnostics
• Features a flexible integrated tracking DC-DC controller optimized for low-cost capacitive boost designs
• Provides software-programmable parameters for ringing, impedance, and loop feed characteristics

Telecom Applications

• VoIP Gateways and Routers
• xDSL Integrated Access Devices (IADs)
• Optical Network Terminals/Units (ONT/U)
• Analog Terminal Adapters (ATA)

Telecom Procurement Notes

Verify the specific ZM2 suffix requirements during procurement, as this indicates a customer-specific configuration distinct from standard commercial or industrial grades. Confirm that the ordering documentation explicitly references the Si32193-A-ZM2 part number to ensure correct firmware and parameter loading. Standard evaluation boards may not be directly compatible without verification of the custom configuration.

Telecom Selection Notes

Select the Si32193-A-ZM2 when DTMF detection capabilities are required alongside wideband audio support. This variant is suitable for applications needing a 3-wire ISI interface and operation within the 0 to 70 °C commercial temperature range. Ensure the host system can support the 3.3 V logic levels and the specific customer-defined parameters associated with the ZM2 designation.

Telecom Part Context

The Si32193-A-ZM2 belongs to the Si3219x series of ProSLIC devices, which are designed to replace traditional discrete FXS solutions. It serves as a direct upgrade path for legacy telephony interfaces, offering reduced component count and lower power consumption. The ZM2 suffix denotes a specific customer-customized version within the commercial grade lineup, sharing the same physical footprint and core functionality as the standard Si32193-A-FM1.

Telecom Replacement Considerations

Publicly confirmed substitute part numbers are not available for the customer-specific Si32193-A-ZM2 variant. Designers should consult Skyworks Solutions for potential cross-references or updated components that meet the specific functional and electrical requirements of this customized part.
