SI32392-B-GM

Telecom Overview

The SI32392-B-GM is a dual-channel Subscriber Line Interface Circuit (SLIC) manufactured by Skyworks Solutions. Designed for analog telephony applications, it integrates two FXS ports within a single QFN-48 package. The device operates on a supply voltage range of 3.15 V to 3.45 V and supports an operating temperature range from 0°C to +70°C. It features surface-mount installation suitable for automated assembly processes. As part of the PROSLIC family, this component provides essential interface functions for connecting subscriber lines to digital systems in telecommunications infrastructure.

Telecom Feature Summary

• Integrates two independent FXS channels for simultaneous subscriber line interfacing
• Supports analog telephony protocols within a compact QFN-48 footprint
• Operates within standard low-voltage DC power requirements

Telecom Applications

• POTS (Plain Old Telephone Service) gateways
• Analog telephone adapters (ATA)
• Central office subscriber line equipment

Telecom Procurement Notes

Verify the specific suffix against official Skyworks documentation to confirm pinout compatibility and electrical characteristics. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with current datasheets to validate manufacturing status and any recent design changes before finalizing orders.

Telecom Selection Notes

Select this component when dual-channel analog interface capability is required in a space-constrained design. Verify that the application environment remains within the specified 0°C to +70°C operational temperature range. Confirm that the system power supply strictly adheres to the 3.15 V to 3.45 V input limits to ensure proper functionality and longevity of the integrated circuits.

Telecom Part Context

This component belongs to the SI3239x series of PROSLIC devices, which are widely used in legacy and hybrid telecommunications systems. The B-GM suffix indicates a specific variant within this family, typically denoting the package type and temperature grade. It serves as a bridge between digital processing units and traditional analog telephone handsets or fax machines.

Telecom Replacement Considerations

Direct substitutes within the same PROSLIC family may offer similar pinouts but require verification of electrical parameter alignment. Check Skyworks documentation for any updated revisions that might supersede this specific part number while maintaining functional equivalence.
