BCM5762B0KMLG

Overview

The Broadcom BCM5762B0KMLG is a Gigabit Ethernet controller designed for network connectivity in computing systems. It integrates a high-performance MAC and PHY to support 10/100/1000 Mbps data rates over standard copper cabling. The component features an integrated five-in-one card reader interface, allowing direct connection to SD, MMC, MS, and other memory card formats without external controllers. It supports PCI Express Gen 2 x1 interface for host communication and includes advanced power management capabilities such as Wake-on-LAN and Energy-Efficient Ethernet (IEEE 802.3az) to reduce power consumption during idle states.

Feature Summary

• Integrated five-in-one card reader interface supporting multiple memory card standards
• High-performance Gigabit Ethernet MAC and PHY with IEEE 802.3 compliance
• PCI Express Gen 2 x1 host interface for reliable data transfer
• Advanced power management including Wake-on-LAN and Energy-Efficient Ethernet

Applications

• Desktop and all-in-one PC mainboards
• Industrial control systems requiring robust network connectivity
• Embedded computing platforms with integrated storage expansion needs
• Network infrastructure equipment requiring low-power operation

Procurement Notes

Verify the exact suffix and package type against the manufacturer's current datasheet, as revisions may affect pin compatibility. Confirm availability status, as older silicon generations may be subject to discontinuation notices or limited stock from authorized distributors. Ensure that the design-in process accounts for any specific termination requirements for the PCIe and card reader interfaces.

Selection Notes

Select this component when a single-chip solution is required for both Gigabit networking and multi-format memory card reading. It is suitable for designs where board space is constrained and minimizing external components is a priority. Consider thermal performance and signal integrity requirements for the PCIe and high-speed memory interfaces during layout.

Part Context

This part belongs to Broadcom's NetXtreme-I series of Ethernet controllers, which are widely used in enterprise and consumer electronics. The BCM5762 variant specifically targets cost-sensitive applications that still require full Gigabit speeds and integrated peripheral connectivity. It represents a mature technology node optimized for reliability and integration density.

Replacement Considerations

Check for newer revisions within the BCM576x family or alternative Broadcom controllers like the BCM57762 if additional features are needed. Verify pin-to-pin compatibility before substituting with competitors' parts, as interface protocols and voltage levels may differ.
