AQR113-B0-C

Overview

The AQR113-B0-C is a single-port, multi-gigabit Ethernet PHY transceiver manufactured by Marvell (Aquantia) using 14nm FinFET technology. It supports line rates of 10GBASE-T, 5GBASE-T, 2.5GBASE-T, 1000BASE-T, 100BASE-TX, and 10BASE-Te over standard copper cabling. The device integrates an advanced DSP engine for high-performance signal processing and includes a built-in MAC controller interface via PCIe Gen 4 x4. It features low power consumption and supports daisy-chaining with other devices in the series for simplified firmware management.

Feature Summary

• Integrated multi-gigabit PHY with advanced DSP for superior signal integrity
• Supports backward compatibility with legacy Ethernet standards
• Low power architecture optimized for thermal efficiency
• Daisy-chain capability for shared firmware storage

Applications

• High-speed desktop and workstation networking
• Enterprise switch and router uplinks
• Industrial automation control systems
• Data center server connectivity

Procurement Notes

Verify the specific suffix 'B0' against official Marvell documentation to confirm pinout and electrical characteristics. Ensure the required external SPI flash memory is compatible with the daisy-chain configuration if multiple PHYs are used. Confirm package type FCBGA-224 availability from authorized distributors.

Selection Notes

Select this component when 10Gbps performance over Cat5e/Cat6 copper is required. Compare with AQR114 or AQR115 if lower speeds suffice to reduce cost. Ensure the host system supports Clause 45 MDIO access for proper register configuration. Verify that the PCB layout accommodates the 14nm FinFET process requirements.

Part Context

This part belongs to the Aquantia Alaska family of multi-gigabit Ethernet controllers. It shares architectural similarities with the AQR114 and AQR115 but offers higher maximum throughput. The 'C' suffix typically denotes a smaller 7mm x 7mm package variant compared to non-C versions.

Replacement Considerations

Direct substitutes include AQR113-A0-C or AQR113-D0-C depending on the specific package and speed requirements. Cross-referencing with AQR114 is necessary if 5Gbps is the maximum needed rate.
