Mingjiada supplies and purchases Asmedia ASM2480B 16Gbps PCIe 4.0 switches, resolving the challenge of bandwidth allocation between motherboard expansion slots and M.2 interfaces
With the explosive growth in demand for AI computing and high-speed storage, PCIe 4.0 switch chips are becoming indispensable ‘data hubs’ in motherboards, servers and edge computing devices. Shenzhen Mingjiada Electronics Co., Ltd. is now supplying and purchasing Asmedia (Xiangshuo Technology) ASM2480B 16Gbps 16-to-8-channel PCIe 4.0 switch chips at competitive prices, providing global customers with a one-stop solution ranging from product selection and procurement to inventory realisation.
Product Overview: Key Specifications of the ASM2480B
The ASM2480B is a 16-to-8-channel multiplexer/demultiplexer (Mux/DeMux) switch chip launched by Asmedia, supporting signal transmission rates of up to 16 Gbps. This device is a bidirectional differential signal switcher capable of multiplexing differential signals to one of two corresponding outputs, and is designed for high-speed applications under the PCI Express Revision 4.0 standard.
In terms of packaging, the ASM2480B is available in 42-pin or 40-pin QFN packages, complies with the RoHS environmental standard, and operates at a supply voltage of +3.3V. The chip features a signal enable function, enabling rapid switching for high-speed, high-bandwidth differential protocols.
Technical Highlights and Competitive Advantages
The core value of the ASM2480B lies in the combination of its 8-channel 2:1 Mux/DeMux architecture with a high signal rate of 16 Gbps. Compared to similar PCIe 4.0 switch chips on the market, the ASM2480B excels in terms of channel density and signal integrity, enabling precise routing of high-speed differential signals whilst maintaining low power consumption.
From a system design perspective, the chip supports bidirectional signal transmission, meaning that a single chip can function as both a multiplexer and a demultiplexer, offering hardware engineers flexible topological design options. Furthermore, the Hi-Z output feature effectively reduces signal crosstalk between channels, ensuring the stability of PCIe 4.0 links during high-frequency operation.
Application Scenarios: From Consumer Motherboards to Data Centres
1. Dynamic Allocation of PCIe Bandwidth on Consumer-Grade Motherboards
The most typical application scenario for the ASM2480B is bandwidth switching between PCIe expansion slots and M.2 interfaces on high-end motherboards. In motherboard designs utilising the B650 chipset, two ASM2480B chips are employed to switch the PCIe 4.0 x4 lane provided by the chipset between the PCIEX16_2 slot and the M2_3 interface. This means users can flexibly allocate the limited PCIe lanes to either a discrete graphics card or a high-speed NVMe solid-state drive, depending on their actual requirements.
2. Server and Storage Expansion
In server and storage systems, the core function of a PCIe switch chip is to ‘expand’ a single PCIe root port into multiple downstream ports, enabling ‘one-to-many’ device connections. With a signal rate of 16 Gbps and 8-channel switching capability, the ASM2480B can be used in NVMe storage expansion cards, internal interconnects for GPU servers, and embedded high-performance computing platforms, enabling systems to connect more SSDs, network cards or accelerator cards despite limited PCIe lane resources.
3. Edge Computing and Industrial Embedded Computing
Edge AI devices and industrial embedded computing platforms have a strong demand for flexible allocation of PCIe lanes. The ASM2480B’s compact QFN package and low-power characteristics make it an ideal choice for edge servers, industrial gateways and embedded communication platforms, enabling reliable switching of high-speed differential signals within a compact board space.
