Mingjiada (Supply/Purchase) ASMedia ASM1465 5G USB 3.0 Repeater (20-Pin) Product Introduction and Features

I. Product Overview

The ASM1465 is a single-channel (dual-channel) 5 Gbps SuperSpeed USB repeater chip developed by ASMedia Technology in Taiwan. It features a compact, eco-friendly 20-pin QFN package and is specifically designed to restore and optimize signal quality for SuperSpeed USB interfaces across various physical media. This chip is fully compatible with the Universal Serial Bus 3.0 Revision 1.0 specification and is widely used in USB 3.0 active extension cables, docks, and high-speed signal link designs.

Shenzhen Mingjiada Electronics Co., Ltd., as a globally renowned authorized independent distributor of electronic components, provides a long-term, stable supply of brand-new, genuine ASM1465 chips in stock. At the same time, the company purchases related excess inventory globally, offering one-stop supply chain services—including both supply and procurement—to customers in the storage devices, consumer electronics, and industrial control sectors.

II. Key Features

The ASM1465 features the following key characteristics:

SuperSpeed USB Compatibility: Fully compliant with the USB 3.0 Specification Revision 1.0, supporting SuperSpeed signal relaying and shaping.

Dual Differential Signal Channels: Integrates two pairs of differential signal channels, supporting a 5 Gbps transmission bandwidth to meet the high-speed data transfer requirements of USB 3.0.

100-ohm Differential CML Input/Output: Utilizes standard 100-ohm differential CML interfaces to ensure signal integrity and impedance matching.

Integrated Receiver Detection Circuit: Features a built-in receiver detection function that automatically identifies the connection status of downstream devices.

Automatic Input Signal Detection and Level Squelch: Supports automatic input signal detection and Level Squelch, effectively filtering out noise interference and enhancing signal reliability.

Configurable/Programmable Output Emphasis Control: Output emphasis can be adjusted via configuration or programming to accommodate transmission cables of varying lengths and materials.

Intelligent Power-Down Management: Supports intelligent power management, automatically entering a low-power state when no signal is present to effectively reduce overall system power consumption.

SuperSpeed Link Power Management: Supports the USB 3.0 link power management specification.

Flexible Power Supply: Supports 3.3V or 1.2V power supplies, accommodating a variety of system power architectures.

Eco-Friendly Packaging: Features a lead-free, eco-friendly QFN 20L package that complies with RoHS environmental standards.

III. Key Technical Highlights: “Python” Technology

The ASM1465 incorporates ASMedia’s patented intelligent feature—“Python” technology. This technology automatically optimizes signal performance by dynamically adjusting repeater parameters based on the actual transmission environment, ensuring optimal signal integrity across different physical media and cable lengths. This patented technology gives the ASM1465 a significant advantage in active cable and long-distance signal transmission applications, making it the preferred controller chip solution for USB 3.0 active extension cables from well-known brands such as Delock.

IV. Typical Application Scenarios

The ASM1465 is primarily used in the following scenarios:

USB 3.0 active extension cables. The chip is specifically designed for USB 3.0 active extension cables, supporting single-segment extensions of up to 5 meters and multi-segment cascaded extensions of up to 5×5 meters, meeting the needs for long-distance USB device connections.

USB 3.0 Docking Stations and Hubs. In docking station and USB hub designs, the ASM1465 is used to recover signal attenuation caused by PCB traces, connectors, and cables, ensuring that SuperSpeed signals remain stable even after multi-stage extension.

High-Speed Signal Link Repeaters. Suitable for industrial equipment, test instruments, and embedded systems requiring long-distance transmission of USB 3.0 signals, effectively compensating for signal degradation and extending USB 3.0 transmission distances.

Consumer Electronics Peripherals. Can be used for signal enhancement in USB 3.0 peripherals, such as signal conditioning for external storage devices, video capture cards, and high-speed data acquisition modules.
