Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The QCA-8081-1-56MQFN-MT-02-0 provides physical layer functions to transmit and receive data over standard Category 5 (Cat5) or Category 6 (Cat6) unshielded twisted-pair cables. The QCA-8081-1-56MQFN-MT-02-0 includes one SerDes, which can work as 1.25 G SGMII or 3.125 G SGMII+ for connection with MAC.

The QCA-8081-1-56MQFN-MT-02-0 integrates Green ETHOS® power-saving technologies, which significantly save power in both active operation and idle condition. Green ETHOS power-saving schemes include ultralow power in cable unplugged mode or port power-down mode. The QCA8081 supports standard IEEE 802.3az Energy Efficient Ethernet (EEE) for 10BASE-Te, 100BASE-TX, and 1000BASE-T.

Features

10BASE-Te: use reduced transmit amplitude

100BASE-TX and 1000BASE-T: Low Power Idle (LPI) mode to turn off unused analog and digital blocks to save power when data traffic is idle. Furthermore, the Wake-on-LAN (WoL) feature manages and regulates total system power requirements. The QCA8081 supports both IEEE 1588 V2 and synchronous Ethernet to offer a complete time synchronization solution.

Clock synchronization between slave and master by the exchange of PTP packets. Supports IEEE 1588 V2 by offering a packet parser, accurate timestamping, and insertion to support both onestep and two-step clock modes.

Supports synchronous Ethernet by offering clock output recovered from received data on the network-line side. The QCA8081 supports MACsec, which is defined by IEEE 802.1AE to offer hop-by-hop link layer security based on symmetric key AES-GCM encryption and authentication.

• 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.
