AQC111C-B0-C

Overview

The AQC111C-B0-C is a single-port Ethernet controller manufactured by Aquantia Corp, belonging to the AQtion series. It supports multi-gigabit speeds including 10Gbps, 5Gbps, and 2.5Gbps over standard copper cabling. The device integrates both Media Access Control (MAC) and Physical Layer (PHY) functions on a single chip. It utilizes a PCIe interface for host connectivity and is housed in an FCBGA package with dimensions of 12x14 mm. The component complies with IEEE 802.3 standards for Ethernet communication.

Feature Summary

• Integrates MAC and PHY functions for a compact single-chip solution
• Supports variable link speeds up to 10Gbps over twisted pair cables
• Provides PCIe interface connectivity for system integration

Applications

• High-speed network adapters for desktop computers
• Server and storage area network (SAN) connectivity
• Thunderbolt docking stations requiring high-bandwidth Ethernet

Procurement Notes

Verify the specific suffix B0 against official Aquantia documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target motherboard or adapter design regarding power requirements and signal integrity. Confirm availability through authorized distributors as supply levels may fluctuate.

Selection Notes

Select this component when a single-port solution supporting speeds beyond 1Gbps is required without external PHY components. Consider the FCBGA package size constraints during PCB layout. Verify that the host system supports the necessary PCIe lanes and driver environment for optimal performance.

Part Context

This part is part of the Aquantia AQtion family, which includes variants like the AQC107 and AQC113. These controllers are widely used in consumer and enterprise networking hardware to provide multi-gigabit connectivity. The AQC111C variant specifically targets applications requiring balanced performance and power efficiency.

Replacement Considerations

Direct replacements within the same package and functionality include other AQtion series chips such as the AQC107 or AQC113, provided pin compatibility and firmware support are verified. Cross-referencing with Marvell datasheets is recommended as Aquantia was acquired by Marvell.
