SI32260-C-GM2

Telecom Overview

The Skyworks SI32260-C-GM2 is a single-chip dual ProSLIC device implementing two complete foreign exchange station (FXS) telephony interfaces. It operates from a 3.3 V supply and supports PCM/SPI or GCI digital bus interfaces. The device integrates built-in DC-DC converter controllers to optimize battery voltage, reducing heat generation. It features linefeed voltage ratings of -110 V, wideband audio support, and comprehensive self-testing capabilities including metallic loop testing. Available in 47-pin QFN (6x8 mm) or 60-pin QFN (8x8 mm) packages.

Telecom Feature Summary

• Performs all BORSCHT functions for FXS channels
• Integrated DC-DC controllers with direct MOSFET connection
• Supports wideband voice and adaptive ringing
• Includes DTMF generator/decoder and pulse metering

Telecom Applications

• VoIP gateways and routers
• xDSL IADs
• Optical Network Terminals/Units (ONT/U)
• Analog Terminal Adapters (ATA)
