회사 블로그 ASMedia ASM1806/Industrial-Grade ASM1806I PCIe Gen2 Switch Chip—Direct Supply from Stock · High-Priced Buyback: One-Stop Service

In PCIe expansion and high-speed I/O system design, ASMedia’s ASM1806 series switch chips have become a widely adopted entry-level Gen2 solution for 6-channel/4-port expansion scenarios due to their low latency, low cost, and low power consumption. Shenzhen Mingjiada Electronics Co., Ltd. operates a two-way business involving both the supply of brand-new, genuine ASM1806 and industrial-grade ASM1806I chips from stock and the global buyback of these products at premium prices, providing customers in the embedded systems, network expansion, storage control, and industrial control sectors with one-stop supply chain support ranging from procurement to inventory liquidation.

I. ASM1806/ASM1806I: A Practical Choice for Entry-Level PCIe Gen2 Switch Chips

The ASM1806 is a 6-channel packet switch chip in ASMedia’s PCIe Gen2 product line, supporting up to four downstream ports. Its upstream interface supports 1- or 2-channel PCIe connections to the root port, automatically detects channel configuration upon startup, and offers single-channel data rates of 2.5 Gb (250 MB/s) and 5 Gb (500 MB/s). With its upstream PCIe Gen2 ×2 bandwidth, this chip supports the construction of various high-speed I/O systems, including servers, system storage, and communication platforms.

The ASM1806 (Standard Edition) and ASM1806I (Industrial Grade) share the same core architecture; the key difference lies in their operating temperature ranges: the ASM1806 is commercial-grade, operating from 0°C to 70°C, while the ASM1806I is industrial-grade, operating from -40°C to 85°C, making it suitable for harsh industrial control and embedded environments. Both models utilize a 10×10 mm QFN88 package. In a 6-channel PCIe Gen2 switch, the ASM1806I typically consumes approximately 2.8 W and offers a theoretical total bandwidth of approximately 30 Gbps (3.75 GB/s), positioning it as a cost-effective solution for low-cost, low-bandwidth expansion scenarios.

In terms of power management and reliability, the ASM1806 series supports L0s/L1/L23/L3 power-saving states, deep power-saving mode in L1 sub-states, S3/S4 wake-up, independent port disable control, LTR, AER, and upstream/downstream SRIS, with a maximum payload of 512 bytes, and supports hot-plugging and accidental removal. These features make it highly suitable for system integration in compact expansion cards and embedded carrier boards.

In terms of actual deployment, the ASM1806 already has proven implementation cases: several PCIe ×4-to-USB expansion cards use the ASM1806 as the switch chip, paired with the Renesas uPD720202 to achieve four-port USB 5 Gbps expansion; On the network expansion side, the Radxa Taco CM4 carrier board utilizes the ASM1806 to enable flexible allocation between dual Ethernet ports (1G + 2.5G) and M.2 NVMe interfaces; the Jiebo JADM2M2G5DL M.2 2.5GbE daughter card also employs the ASM1806, integrating dual Intel I225-V 2.5GbE interfaces. These applications demonstrate that the ASM1806 is a practical choice that balances cost and bandwidth in scenarios such as USB expansion, multi-port network cards, multi-bay NVMe adapters, and industrial PC PCIe device expansion.

II. Mingjiada Electronics: A Stable Supply Channel for the ASM1806 and ASM1806I

Founded in 1996, Mingjiada Electronics has been deeply involved in the distribution and recycling of electronic components for nearly three decades. With inventory resources comprising over 2 million SKUs, the company provides a long-term, stable supply of the full range of ASMedia PCIe switch chips. Mingjiada maintains the ASM1806 and ASM1806I as standard in-stock items. These products are brand-new and factory-sealed, capable of meeting bulk procurement needs across embedded systems, servers, network expansion, and industrial control sectors. Both chips are available in QFN88 packaging, allowing customers to select models flexibly based on operating temperature ratings.

In terms of delivery capabilities, Mingjiada leverages its headquarters in Shenzhen’s Huaqiangbei district and a network of branch offices in Hong Kong, Japan, Russia, Taiwan, and other locations to support rapid responses to urgent orders. For customers needing to purchase both the ASM1806 and ASM1806I simultaneously, Mingjiada offers a supply solution through a single channel with unified quality control, reducing the lead time and quality control costs associated with fragmented procurement from multiple suppliers.

III. High-Priced Buyback of ASM1806: Quickly Convert Idle Inventory into Cash

Changes in electronics manufacturing projects, order cancellations, or excess inventory often result in original-packaged chips such as ASM1806 and ASM1806I accumulating in warehouses. Mingjiada Electronics operates both supply and buyback businesses, leveraging its procurement and buyback channels to provide competitive buyback quotes based on real-time market supply and demand as well as international component market trends—rather than vague estimates disconnected from market conditions.

For ASM1806/ASM1806I, Mingjiada’s buyback service covers a wide range of sources, including factory inventory, project surplus, distributor overstock, and personal inventory. We provide quotes for original factory-sealed reels, palletized stock, and loose components. Specific advantages include:

Quotes 5%–15% above the market average, with full payment within 24 hours after successful inspection;

We support both cash and corporate bank transfers, and handle both large and small batches. For customers in the Pearl River Delta region, we offer on-site inspection; customers outside the region can receive quick online estimates via inventory lists and photos;

We use an A/B/C grading system for factory inventory, with reasonable pricing logic for different conditions—such as factory-sealed items, packaging with minor damage, or items with cosmetic defects—ensuring the minimum value for each material category is clearly documented;

We provide end-to-end coordination throughout the entire process—from valuation and inspection to pickup and settlement—eliminating the hassle of customers having to sort items themselves or shop around for the best price.

For companies and traders holding ASM1806/ASM1806I inventory, choosing a recycler with both genuine procurement channels and pricing expertise is a critical step in avoiding price pressure from middlemen and maximizing the value of their inventory.

Conclusion

As entry-level switch chips that have been volume-proven in PCIe Gen2 expansion scenarios, the supply stability and inventory liquidity of the ASM1806/ASM1806I directly impact project timelines and capital efficiency. Backed by nearly 30 years of supply chain expertise, Mingjiada Electronics has established two parallel channels for ASM1806/ASM1806I: “direct supply of genuine spot inventory” and “high-value global buyback.” Customers seeking to purchase can access readily available stock and fast delivery, while those looking to dispose of inventory can receive market-competitive quotes and efficient settlement.
