BCM53134OKFBG

Overview

The BCM53134OKFBG is an ultra-low power Gigabit Ethernet switch manufactured by Broadcom Limited. It features six integrated transceivers and supports data rates of 10 Mb/s, 100 Mb/s, 1 Gb/s, and 2.5 Gb/s. The device complies with standards including 10/100/1GBASE-TX, 100/1G/2.5GBASE-FX, and 1G/2.5GBASE-X. It utilizes RGMII and SGMII interface types for host connectivity. Operating within a temperature range of 0°C to +70°C, the component requires a supply voltage of 1 V. It is housed in an FBGA-256 package designed for surface mount technology.

Feature Summary

• Supports 2.5 Gbps SGMII interfaces to accommodate bandwidth growth and 802.11ac deployments
• Integrates an on-chip 8051 microcontroller for cable diagnostics and green energy-saving modes
• Provides compact field processor entries for efficient rule processing

Applications

• High-performance enterprise routers and switches
• Industrial control systems requiring robust network connectivity
• Network Attached Storage (NAS) devices
• Smart home hubs and gateways

Procurement Notes

Verify the specific suffix OKFBG against official datasheets to confirm package type and temperature grade. Ensure compatibility with required PCB footprint dimensions for the FBGA-256 configuration. Confirm that the 1V power supply design meets the current requirements specified in the electrical characteristics table.

Selection Notes

Select this component when integrating six-port switching capabilities with support for 2.5G uplinks. Consider the integrated PHY functionality which reduces external component count. Evaluate the thermal performance within the 0°C to +70°C commercial range against the target application environment constraints.

Part Context

This part belongs to the Broadcom BCM5 series, a family of high-performance Ethernet switches. It serves as a specialized solution for multi-port networking applications, distinct from single-port PHYs or lower-density switch controllers. The model represents a balance of port density and advanced feature sets like Green Ethernet.

Replacement Considerations

The BCM53134SIFBG is a documented variant within the same product line. Verify pinout compatibility and functional equivalence before substitution. Other models in the BCM531xx series may offer different port counts or feature sets.
