BCM63155B1VKFSBG

Overview

The BCM63155B1VKFSBG is a network controller and processor IC manufactured by Broadcom Limited. It integrates bonded 35B technology to support V/ADSL and VoIP applications. The device functions as a standalone network controller without an integrated SPU (Security Processing Unit). It belongs to the Communication & Networking ICs sub-category under Network Controller & Processor ICs. The component is RoHS compliant and utilizes a specific package configuration designated by the suffix.

Feature Summary

• Integrates bonded 35B architecture for enhanced processing capabilities within a single chip solution.
• Supports Voice over IP (VoIP) functionality alongside V/ADSL connectivity standards.
• Designed as a network controller processor IC without an integrated Security Processing Unit (SPU).

Applications

• V/ADSL modem gateways
• VoIP residential gateway devices
• Network controller embedded systems

Procurement Notes

Verify the exact package type and thermal specifications against the official datasheet before integration, as the suffix indicates specific physical attributes. Confirm that the absence of an integrated SPU aligns with the security requirements of the target design, as external security handling may be necessary. Ensure compatibility with the intended ADSL/VoIP interface standards.

Selection Notes

Select this component when a dedicated network controller processor for V/ADSL and VoIP is required without internal security processing hardware. Compare against other Broadcom BCM63xxx series variants if SPU integration or different DSL standards are needed. Verify pinout compatibility and power supply requirements specific to the VKFSBG package variant during the schematic capture phase.

Part Context

This part belongs to the Broadcom BCM63xx family of broadband processors, which are widely used in telecommunications equipment. The BCM63155 variant specifically targets the V/ADSL market segment. The B1VKFSBG suffix denotes the specific temperature grade, package style, and lead-free status defined by the manufacturer's ordering nomenclature system.

Replacement Considerations

Direct substitutes within the same family require matching the SPU configuration and DSL standard support. Check for suffix variations that indicate identical electrical performance but different packaging or temperature ranges. Cross-reference with Broadcom's obsolescence notices for alternative recommendations if this specific suffix is discontinued.
