Mingjiada Electronics has the ASM1464 USB 3.0 signal repeater in stock—specifically designed for high-speed signal transmission in laptop motherboards, docking stations and gaming laptops
ASM1464 Product Overview
The ASM1464 is a single-channel (dual differential pairs) 5 Gbps SuperSpeed USB 3.0 signal repeater (Repeater/ReDriver) launched by ASMedia (Xiangshuo Technology), utilising an environmentally friendly 24-pin QFN package. This device is specifically designed to address signal attenuation and integrity degradation issues that arise when high-speed USB signals are transmitted over long distances or pass through complex physical media (such as PCB traces and connecting cables).
The ASM1464 is widely used in applications such as laptop motherboards, gaming laptop sub-boards, USB docking stations and desktop front-panel USB ports to ensure the reliable transmission of USB 3.0 signals both within devices and via external interfaces.
Mingjiada Electronics maintains a long-term stock of the ASM1464; all products are genuine, with ample stock available and rapid delivery supported.

ASM1464 Key Features
1. SuperSpeed USB 3.0 Compatibility
The ASM1464 is fully compatible with the USB 3.0 specification, supporting a maximum data transfer bandwidth of 5 Gbps to meet the data throughput requirements of high-speed peripherals.
2. Integrated Receiver Detect Circuit
The built-in Receiver Detect Circuit automatically identifies the status of the receiving device, optimising the signal transmission path.
3. Automatic Input Signal Detection and Level-Squelch
Supports automatic input signal detection and level-squelch functions, effectively filtering out invalid signals and noise to ensure the stable transmission of valid signals.
4. Configurable/Programmable Output Emphasis Control
It provides configurable/programmable output emphasis control, allowing the signal shaping intensity to be flexibly adjusted according to different PCB trace lengths and dielectric properties.
5. ASMedia’s Patented ‘Python’ Technology
The ASM1464 integrates ASMedia’s patented intelligent feature—‘Python’ technology—which automatically optimises signal performance to achieve optimal signal quality under various physical medium conditions.
6. SuperSpeed Link Power Management
Supports SuperSpeed Link Power Management, automatically reducing power consumption during idle periods to meet the energy-saving requirements of mobile devices.
7. Low-Power 3.3V Power Supply
Powered by a single 3.3V supply, it offers low power consumption, making it suitable for power-sensitive laptop and mobile device designs.
ASM1464 Typical Application Scenarios
1. Laptop and Gaming Laptop Motherboards
The ASM1464 is widely used on laptop and gaming laptop motherboards to relay USB 3.0 signals, ensuring signal integrity for both front and rear USB ports on the motherboard. In some high-end gaming laptops, as many as two ASM1464 signal repeaters are even employed to relay USB signals and boost the power supply.
2. USB 3.0 Signal Shaping on Motherboards
On desktop motherboards, the ASM1464 is often deployed as a USB 3.0 re-driver near USB ports where PCB traces are long or where external output is required, to shape and amplify the signal. For example, the front and rear USB 3.2 Gen 1 ports on the ASUS ROG Crosshair VIII Impact motherboard utilise the ASM1464 as the ReDriver IC.
3. USB Docking Stations and Front Panels
The ASM1464 is suitable for use in USB docking station and desktop front-panel USB designs, compensating for signal attenuation caused by internal flex cables or extension cables to ensure stable connections with external devices.
4. USB 3.0 Extension Cables
In USB 3.0 extension cable products, the ASM1464 can be used as a signal amplification and relay chip, supporting connections to various USB devices such as external hard drives, mobile phones, tablets, USB flash drives, card readers, mice and keyboards.
5. Long-Distance Signal Transmission Applications
The ASM1464/65 series of USB 3.0 signal regenerator chips are specifically designed to re-amplify signals and stabilise signal quality during long-distance transmission, effectively improving the interoperability of peripheral devices.
