AQR411C-B0-C

Overview

The AQR411C-B0-C is a quad-port, 5Gbps Ethernet PHY transceiver from the Marvell AQrate GEN3 family. It supports 5GBASE-T, 2.5GBASE-T, 1000BASE-T, and 100BASE-TX standards over Cat 5e or better cabling exceeding 100 meters. The device integrates Energy Efficient Ethernet (EEE), Synchronous Ethernet (Sync-E), Precision Time Protocol (PTP)/1588v2, MACsec (IEEE 802.1ae), Wake-on-LAN, and advanced cable diagnostics. It accommodates all PoE standards up to 100W and jumbo packets up to 16KB. The component is housed in a 14 x 12 mm package.

Feature Summary

• Supports Multi-Gigabit speeds over existing Cat 5e and Cat 6 infrastructure
• Integrates comprehensive security and synchronization protocols
• Includes built-in thermal management and diagnostic capabilities

Applications

• Network switches
• Enterprise access points
• Carrier premises equipment
• Home gateways

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm exact package and temperature specifications. Ensure compatibility with system power requirements for PoE applications up to 100W. Confirm interface alignment with host controllers supporting XFI, USXGMII, or SERDES connections.

Selection Notes

Select this quad-port variant when multiple high-speed ports are required within a compact footprint. Compare against single-port models like the AQR111C if fewer ports suffice. Consider the 14 x 12 mm package dimensions during PCB layout planning relative to available board space.

Part Context

This component belongs to the Marvell AQrate GEN3 series, designed for multi-gigabit connectivity. It complements other family members like the AQR412C and AQR111C by offering quad-port density at 5Gbps speeds. The series targets enterprise and carrier markets requiring robust wired solutions.

Replacement Considerations

Direct substitutes include the AQR412C for quad-port 2.5Gbps applications or the AQR111C for single-port 5Gbps needs. Verify pinout and software compatibility before swapping between different port counts or speed variants within the same generation.
