BCM5720A0KFBG

Overview

The BCM5720A0KFBG is a dual-port Gigabit Ethernet PHY transceiver manufactured by Broadcom Limited. It supports data rates of 10 Mb/s, 100 Mb/s, and 1 Gb/s over copper media. The device integrates two independent transceivers and interfaces with host processors via RGMII or SGMII protocols. It operates within a commercial temperature range of 0°C to 55°C and utilizes a BGA-135 surface-mount package. Power requirements include 1 V and 3.3 V supplies.

Feature Summary

• Dual-port architecture providing integrated Gigabit Ethernet connectivity on a single chip
• Support for standard Ethernet speeds including 10/100/1000BASE-T operation
• Flexible host interface compatibility with RGMII and SGMII standards

Applications

• Dual LAN port implementations in embedded motherboards
• Network interface cards requiring compact form factors
• Industrial gateways needing reliable copper-based Ethernet connectivity

Procurement Notes

Verify the specific ordering suffix against official Broadcom documentation to confirm package type and temperature grade. Ensure supply chain partners provide valid RoHS compliance certificates. Confirm that the component meets moisture sensitivity level requirements for your assembly process before procurement.

Selection Notes

Select this component when a dual-port solution is required to reduce PCB area compared to single-port alternatives. Verify that the host controller supports either RGMII or SGMII interfaces for proper integration. Ensure the system design accommodates the necessary 1 V and 3.3 V power rails specified for operation.

Part Context

This part belongs to the Broadcom NetXtreme family of networking components. It serves as a physical layer transceiver designed to bridge copper cabling infrastructure with digital baseband processing units. The component is distinct from switch fabrics or MAC controllers, focusing solely on signal transmission and reception.
