ASM1074 Genuine Stock Available: USB 3.2 Gen1 Four-Port Hub Controller for Computer Motherboards, Docking Stations and Industrial Control — Mingjiada, Shenzhen Stock Supplier

With the ever-increasing demand for high-speed data transfer via USB interfaces and multi-device connectivity, a high-performance, highly compatible USB hub controller has become central to system design. The ASM1074 is a highly integrated USB 3.2 Gen1 four-port hub controller launched by ASMedia Technology, supporting SuperSpeed data transfer rates of up to 5 Gbps. As a Shenzhen stock supplier, Mingjiada Electronics has long supplied genuine ASM1074 chips, providing a reliable supply of chips for sectors including computer motherboards, USB docking stations, industrial control systems and consumer electronics.

I. ASM1074 Product Overview

The ASM1074 is a four-port USB hub controller that highly integrates ASMedia’s proprietary SuperSpeed USB 3.0 and USB 2.0 PHYs (physical layer interfaces), complying with the USB 3.0 Revision 1.0 specification. The chip is housed in a 10×10 mm² 88-pin QFN package and complies with the environmentally friendly RoHS standards.

The ASM1074 not only expands a single USB 3.0 port into four high-speed ports, but also provides comprehensive power management, support for charging protocols and flexible customisation capabilities, making it an ideal choice for all types of electronic devices requiring USB port expansion.

III. ASM1074 Typical Application Scenarios

Thanks to its high performance, high compatibility and flexible configuration capabilities, the ASM1074 is widely used in the following areas:

1. Computer motherboards – USB port expansion

The ASM1074 is widely used in high-end desktop and server motherboards. Motherboard manufacturers utilise a single ASM1074 chip to expand the one or two native USB 3.0 ports provided by the CPU or chipset into four USB 3.0 ports, significantly increasing the number of USB ports on the motherboard. For example, the ASM1074 can be found as a third-party USB 3.0 hub chip on numerous motherboards featuring Z87, X99 and X299 chipsets from brands such as ASUS, ASRock and MSI.

2. USB Docking Stations and Splitters

The ASM1074 serves as the core controller solution for USB docking stations and USB splitters. In USB docking stations priced at around 100 yuan, a single ASM1074 chip can provide four USB 3.0 ports; when paired with a capacitive filtering architecture, it maintains the integrity of USB 3.0 signal channels even with a 1.5-metre cable.

3. PCIe USB Expansion Cards

The ASM1074 is frequently used in conjunction with ASMedia’s USB host controllers (such as the ASM1042) to form PCIe USB 3.1 Gen 1 expansion cards, adding four USB-C or USB-A ports to desktop computers and workstations. These support connections to devices such as USB hard drive enclosures, docking stations, KVM switches, VR systems and USB graphics adaptors.

4. Industrial Control Systems

In industrial automation and equipment management scenarios, the ASM1074 is used to support the connection and management of USB devices within industrial systems, meeting the demands of industrial environments for simultaneous access to multiple USB devices and stable communication.

5. Consumer Electronics

The ASM1074 is also widely used in consumer electronics such as monitors, smart TVs and gaming devices, providing these devices with enhanced USB connectivity.
