Le blog de l'entreprise Mingjiada Electronics Supply and Acquisition of ASM1824: 24-channel/12-port PCIe Gen 2 Packet Switching Chip

Against the backdrop of ever-increasing demand for high-speed I/O expansion in servers, storage systems and communication platforms, PCIe packet switch chips play a crucial role as ‘data hubs’. The ASM1824, launched by ASMedia, is a 24-channel PCIe Gen2 packet switch chip designed for mid- to high-end I/O expansion scenarios. Shenzhen Mingjiada Electronics Co., Ltd., a globally renowned authorised independent distributor of electronic components, has long provided a stable supply of ASMedia’s full range of PCIe switch chips, whilst also purchasing surplus stock globally. For the ASM1824, Mingjiada Electronics offers brand-new, original off-the-shelf stock and high-value buy-back services, providing a one-stop supply chain solution for customers in the server, storage and communications equipment sectors.

ASM1824 Product Overview

The ASM1824 is a low-latency, low-cost, low-power 24-channel PCIe Gen2 packet switch chip launched by ASMedia, supporting up to 12 downstream ports. Leveraging upstream PCIe Gen2×8 bandwidth, this chip enables users to build a variety of high-speed I/O systems, with typical applications spanning servers, system storage and communications platforms. The chip is housed in a 21×21 LFBGA package with 492 pins, and the product package designation is LFBGA492.

Detailed Core Features

Flexible Lane and Port Configuration

The ASM1824 supports connection to the root port via 1, 2, 4 or 8 PCIe lanes and automatically detects the lane configuration at boot-up, adapting to different system architectures without the need for manual intervention. The chip provides 16 PCIe 2.0 lanes and supports up to 12 PCIe ports, offering ample physical lane resources for the parallel expansion of multiple devices.

Dual-Rate Transmission Support

The chip supports two transmission rates per lane: 2.5 Gb (250 MB/s) and 5 Gb (500 MB/s). It is compatible with the varying link speed requirements under the PCIe Gen 2 standard, allowing bandwidth to be flexibly matched to actual workload demands.

Comprehensive Power Management

The ASM1824 offers comprehensive power management capabilities for power consumption control: it supports L0s, L1, L23 and L3 power-saving states, as well as deep power-saving modes within the L1 sub-states, and wake-up functionality in S3 and S4 states. These features enable it to effectively reduce standby power consumption in server and storage systems, meeting the stringent energy efficiency requirements of green data centres.

Advanced Features and Reliability

The chip supports individual port disable control, LTR (Latency Tolerance Reporting), AER (Advanced Error Reporting), and SRIS (Standalone Reference Clock Architecture) on both upstream and downstream ports. With a maximum payload size of 512 bytes and support for hot-swapping and accidental disconnection protection, it offers greater flexibility for system operation and maintenance.

Typical Application Scenarios

With its 24-channel high-density switching capability and low-latency characteristics, the ASM1824 offers extensive application value across multiple sectors. In terms of server I/O expansion, the chip can be used to increase the number of PCIe slots, meeting the demand for parallel access to multiple network interface cards and accelerator cards; in the field of system storage, it can be utilised for NVMe SSD expansion and storage controller cascading; whilst on communication platforms, it serves as a core node for high-speed data exchange.

Mingjiada Electronics’ Supply and Procurement Services

Shenzhen Mingjiada Electronics Co., Ltd. was established in 1996. Headquartered in Huaqiangbei, Shenzhen, the company has branches in Hong Kong, Japan, Russia and Taiwan. With over 2 million stock items, its business covers two main sectors: the supply and recycling of electronic components.

In terms of supply, Mingjiada Electronics, as a long-term and reliable supplier of ASMedia’s full range of PCIe switch chips, can provide brand-new, genuine ASM1824 chips in stock, packaged in LFBGA492. The product’s origin is traceable, ensuring it is a genuine, original item. In addition to the ASM1824, Mingjiada also supplies other ASMedia series switch chips, such as the ASM2824 (PCIe Gen3, 24-channel) and ASM1184 (PCIe Gen2, 4-port), meeting customers’ requirements for a complete product line ranging from Gen2 to Gen3.

In terms of procurement, Mingjiada Electronics has long specialised in the global recycling of surplus stock related to ASMedia PCIe switch chips.
