Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The QCA8081 is a single-port, four-rate (10M/100M/1G/2.5G) Ethernet PHY transceiver. The QCA8081 provides physical layer functionality to transmit and receive data over standard Class 5 (Cat5) or Class 6 (Cat6) unshielded twisted pair cables. The device includes a SerDes that can be connected to a MAC as 1.25G SGMII or 3.125G SGMII+.

Features

10BASE-Te: Uses reduced emission amplitude

100BASE-TX and 1000BASE-T: Low Power Idle (LPI) modes turn off unused analog and digital blocks to save power when data traffic is idle. In addition, the Network Wake Up (WoL) function manages and adjusts total system power requirements. The QCA8081 supports IEEE 1588 V2 and synchronous Ethernet, providing a complete time synchronization solution.

Clock synchronization between the slave station and the master station is realized by exchanging PTP packets. Supports IEEE 1588 V2, provides packet resolver, precise timestamp, and insert capabilities, and supports single - and two-step clock modes.

Supports synchronous Ethernet and provides clock output recovered from data received on the network line side. The QCA8081 supports MACsec as defined by IEEE 802.1AE and provides 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.
