Mingjiada Electronics Supplies and Recycles ASMedia ASM1468 | 8Gbps PCIe Redriver

I. ASM1468 Product Overview

The ASM1468 is a dual-channel/4-differential-channel linear redriver launched by ASMedia (Xiangshuo Technology), with a maximum signal rate of 8Gbps, specifically designed for extending PCI Express board traces. The chip employs a four-differential-channel linear re-driver architecture, allowing the receive-end equalisation and DC gain levels to be programmed via function configuration pins. Signal parameters can be set independently for each channel, thereby optimising signal performance and reducing intersymbol interference (ISI) on PCB traces with varying dielectric properties and/or cables. The ASM1468 is designed using a CMOS process, offering low power consumption and high performance. It operates on a single 3.3V power supply and is housed in a 3.5×9mm QFN42 green package that complies with RoHS environmental standards.

II. Key Technical Features

High-Speed Signal Compatibility

The ASM1468 is fully compatible with three PCI Express signal rates: 8 Gbps (Gen3), 5 Gbps (Gen2) and 2.5 Gbps (Gen1). It can flexibly adapt to the requirements of different generations of PCIe links, providing full backwards compatibility for system design.

Flexible Equalisation and Gain Adjustment

The chip supports pin-configurable adjustment of receiver equalisation and transmitter gain. Engineers can independently configure the equalisation and gain parameters for each channel based on actual channel loss characteristics, thereby precisely compensating for signal attenuation caused by varying PCB trace lengths and cable types.

Receiver Termination Detection and Power Management

The ASM1468 supports the Receiver Termination Detection function, which automatically detects the link connection status. It also supports a comprehensive power management mechanism, helping to reduce overall system power consumption and meet green, energy-efficient design requirements.

Compact Packaging and Wide-Temperature Reliability

Housed in a 42-pin QFN package measuring 3.5 × 9 mm², the device features a lead-free design compliant with RoHS standards, making it suitable for board layouts with space constraints.

III. Typical Application Scenarios

The ASM1468’s 8 Gbps PCIe linear redriving capability enables it to play a key role in the following scenarios:

Servers and Data Centres: In rack-mounted servers, microservers and tower servers, where PCIe signals must travel long distances via backplane traces, the ASM1468 effectively compensates for channel loss, ensuring the stable operation of high-speed links between the CPU and NVMe SSDs, GPUs and network adaptors.

Storage Systems: Suitable for storage expansion scenarios such as SANs (Storage Area Networks) and HBA (Host Bus Adapter) cards, ensuring signal integrity for PCIe Gen3 storage devices in complex channel environments.

Industrial Control and Embedded Platforms: In industrial-grade control motherboards and embedded systems, the ASM1468 helps designers address signal attenuation issues under harsh conditions such as high temperatures and long signal runs.

Network Interface Cards: Provides PCIe link signal conditioning for high-performance NICs (Network Interface Cards), ensuring high-speed and reliable transmission of network data.
