AQR112C-B0-C

Overview

The Marvell AQR112C-B0-C is a single-port, Multi-Gigabit Ethernet PHY transceiver designed for high-performance wired connectivity. It supports network rates of 5GBASE-T, 2.5GBASE-T, 1000BASE-T, and 100BASE-TX over twisted pair cabling. The device integrates Energy Efficient Ethernet (EEE), MACsec security, Precision Time Protocol (PTP)/1588v2, and Synchronous Ethernet (Sync-E). It accommodates all Power over Ethernet standards up to 100W and jumbo packets up to 16KB. The component utilizes a compact 7 x 7 mm package.

Feature Summary

• Supports 5GBASE-T and 2.5GBASE-T transmission over more than 100 meters of Cat 5e or better cabling
• Integrates hardware security features including MACsec and Precision Time Protocol support
• Provides advanced cable diagnostics and built-in thermal management capabilities

Applications

• Enterprise switches
• Carrier premises equipment
• Home gateways

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product brief to confirm package dimensions and temperature ratings. Ensure compatibility with IEEE 802.3bz standards for multi-gigabit operation. Confirm that the system design supports the required interface protocols such as XFI or SGMII for proper integration.

Selection Notes

Select this component when a single-port solution is required for speeds up to 2.5Gbps in space-constrained designs. The 7x7mm package offers a smaller footprint compared to the 7x11mm variant. Consider the integrated MACsec and PTP features if security and timing synchronization are critical requirements for the target application.

Part Context

This part belongs to the Marvell AQrate GEN3 family of Ethernet PHYs. The 'C' designation indicates a 7x7mm package, distinguishing it from the standard 7x11mm version. The series focuses on enabling multi-gigabit speeds over existing copper infrastructure while maintaining low power consumption and high integration levels.

Replacement Considerations

The AQR112 serves as the pin-compatible alternative with a larger 7x11mm package. For quad-port requirements, the AQR412C provides similar speed capabilities in a 14x12mm form factor.
