SI3216-C-FT

Telecom Overview

The SI3216-C-FT is a ProSLIC single-channel subscriber line interface concept integrated circuit manufactured by Skyworks Solutions. It supports both broadband and voice telephony applications within a 38-TSSOP surface-mount package. The device operates on a supply voltage range of 3.3V to 5V with a maximum power dissipation of 700 mW. It integrates a CODEC and user line interface functions, communicating via PCM and SPI interfaces. The component is rated for an operating temperature range from 0°C to +70°C.

Telecom Feature Summary

• Integrates single-channel FXS functionality with embedded CODEC capabilities
• Supports both broadband and traditional voice telephony signaling standards
• Features low power consumption suitable for battery-operated or energy-efficient designs

Telecom Applications

• Broadband digital subscriber line (xDSL) modems
• Voice over IP (VoIP) gateways
• Analog telephone adapters (ATA)

Telecom Procurement Notes

Verify the specific suffix 'C-FT' against official Skyworks documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status through the manufacturer's environmental declaration. Check for obsolescence notices as this series may be designated for non-new designs in some distributor catalogs.

Telecom Selection Notes

Select this component when a single-channel analog front-end solution is required for telephony applications. Ensure the design accommodates the 38-pin TSSOP footprint and 3.3V/5V logic levels. Verify that the thermal management strategy supports the 700 mW power dissipation limit within the specified ambient temperature range.

Telecom Part Context

The SI3216 belongs to the ProSLIC family of subscriber line interface circuits. It serves as a complete analog front-end solution, replacing discrete components typically found in traditional telephone systems. This integration reduces board space and simplifies design complexity for telecom equipment manufacturers.

Telecom Replacement Considerations

Consult Skyworks technical support for current active replacements. Previous generations such as the SI3210 or SI3211 may offer similar functionality but require verification of pin compatibility and feature set alignment.
