Mingjiada Electronics | ASMedia ASM1562 USB 3.1 Gen2 10Gbps Single-Channel Retimer: Genuine Products in Stock and High-Priced Buyback

ASM1562 Product Overview

ASMedia’s ASM1562 is a single-channel, dual-differential SuperSpeedPlus USB 3.1 Gen 2 retimer with a maximum signal interface rate of 10 Gbps. It complies with the USB 3.1 Rev 1.0 standard and fully supports USB 3.1 Gen-I and Gen-II.

In high-speed interface designs, signals inevitably experience amplitude attenuation and eye-diagram closure after traveling through long PCB traces, connectors, or cables. The ASM1562 is specifically designed to address this core challenge—it acts as a “signal restorer” in the signal chain, “reopening” the eye diagram at the receiving end to restore signal integrity. It is a critical signal conditioning chip for achieving stable 10 Gbps transmission in server motherboards, high-end graphics cards, expansion cards, and embedded platforms.

ASM1562 Key Technical Features

Adaptive Linear Equalization and Clock-Data Recovery (CTLE + CDR)

The ASM1562 employs advanced adaptive continuous-time linear equalizer (CTLE) and clock-data recovery (CDR) technologies in its receive circuit, enabling dynamic compensation for channel loss, precise recovery of data from degraded input signals, and a significant reduction in bit error rate.

Transmitter-Side De-emphasis and Pre-shooting Drive

The device integrates de-emphasis and pre-shooting drive functions on the transmitter side. By pre-compensating for high-frequency channel losses, it ensures that the signal maintains good eye diagram quality upon reaching the receiver, effectively eliminating input jitter and intersymbol interference (ISI), thereby suppressing noise output.

Flexible Configuration Methods

The ASM1562’s signal performance settings can be configured in two ways: rapid configuration via external strapping pins or programming via the SMBus slave interface, meeting the flexibility and adjustability requirements of various system designs.

Highly Integrated Power Solution

The device integrates a PWM regulator for core power supply and operates on a single 1.8V power supply, eliminating the need for additional power management peripheral circuits. This simplifies system power supply design and reduces BOM costs.

Compact Package and Compliance

The device features an industry-standard QFN-24 (4 mm × 4 mm) green package with a lead-free design that complies with RoHS regulations, making it suitable for high-density PCB layouts and automated surface-mount production.

Typical Applications

The core value of the ASM1562 lies in enhancing signal integrity. It is widely used in the following scenarios that require stable transmission of 10 Gbps signals over long distances or through high-loss channels:

Server and Data Center Motherboards: USB 3.1 Gen2 signals travel through long PCB traces from the chipset to the front-panel interface; the ASM1562 restores the signal along the link, ensuring the port consistently achieves a 10 Gbps data rate.

High-End Graphics Cards and Expansion Cards: Used to compensate for board-level trace loss in USB Type-C outputs on graphics cards or USB ports on PCIe expansion cards.

Laptops and Embedded Platforms: Provides signal conditioning for USB 3.1 Gen2 signals passing through connectors and cables in space-constrained portable devices.

Long-Distance USB Cables and Docking Stations: Acts as the core signal repeater in active USB cable and docking station designs, extending the effective transmission distance.
