AQC108-B1-C

Overview

The AQC108-B1-C is a single-port, six-speed Ethernet controller manufactured by Aquantia Corp. It integrates both Media Access Control (MAC) and Physical Layer (PHY) functions to support data rates of 10Gbps, 5Gbps, 2.5Gbps, 1Gbps, and 100Mbps over standard twisted-pair cabling. The device complies with IEEE 802.3 standards for Multi-Gigabit Ethernet. It utilizes a PCIe interface for host connectivity and is housed in an FCBGA package measuring 12x14 mm. This component serves as a high-performance solution for network infrastructure requiring flexible speed adaptation.

Feature Summary

• Integrates MAC and PHY layers into a single silicon die
• Supports automatic negotiation across five distinct Ethernet speeds
• Provides PCIe interface for low-latency host communication

Applications

• Enterprise network switches and routers
• High-performance server network interfaces
• Industrial automation networking equipment

Procurement Notes

Verify the manufacturer part number against official Aquantia documentation to ensure authenticity. Confirm that the specific suffix matches the required package and temperature grade. Request datasheets directly from authorized distributors or the manufacturer to validate current production status and compliance certifications before finalizing procurement orders.

Selection Notes

Select this controller when a design requires support for legacy 100BASE-TX and 1000BASE-T alongside modern 2.5GBASE-T and 5GBASE-T speeds on a single port. Ensure the host system provides a compatible PCIe lane configuration. Verify that the PCB layout supports the thermal requirements of the FCBGA package and meets signal integrity specifications for 10Gbps operation.

Part Context

This component belongs to the Aquantia AQtion family of multi-gigabit Ethernet controllers. The AQC108 variant specifically targets single-port applications requiring backward compatibility with older copper cabling while delivering higher throughput than standard Gigabit solutions. It complements other models like the AQC107 and AQC109 within the same product line.
