Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The SAS3808N IOC, based on the industry-leading Fusion-MPT™ (Message Passing Technology) architecture, supports up to 8 SAS/SATA devices and up to 2 PCIe devices direct-attached. This Gen 4.0 PCIe x4, 8-port IOC, in a footprint-optimized package, delivers power reductions over previous generations and features Tri-Mode SerDes Technology that enables a seamless operation of SAS, SATA, and NVMe storage devices from any system design. 

The 8-port Tri-Mode IOC device interface provides SAS data transfer rates of 12 and 6 Gb/s per lane, SATA data transfer rates of 6 Gb/s, or PCIe data transfer rates of 16.0, 8.0, 5.0, and 2.5 GT/s. The device automatically negotiates between the speeds and protocols. The SCSI Protection Information for early detection of and recovery from data corruption, and Spread Spectrum Clocking (SSC) for EMI reduction are supported. 

The SAS3808N host interface supports 4 PCI Express (PCIe) lanes and complies with the PCIe 4.0 specification. It also incorporates power management, MSI/MSI-X, and legacy interrupt generation.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
