Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The Marvell® Alaska® 88E1548PA0-BAM2C000 Gigabit Ethernet Transceiver is a physical layer device that includes four independent Gigabit Ethernet transceivers. Each transceiver provides all physical layer functions of 1000BASE-T, 100BASE-TX, and 10BASE-T and is fully compliant with 802.3 standards. On the MAC side of the interface, the device supports Quad Serial Gigabit Media Interface (QSGMII) to copper or fibre, Quad-Port SGMII to copper, or Dual-Port SGMII to fibre.

The 88E1548P version supports the Marvell LinkCrypt® feature based on and implementing the IEEE802.1ae MACsec protocol. This version supports Precision Timing Protocol (PTP) timestamps based on IEEE 1588v2 and IEEE 802.1AS, as well as two-step and one-step clocking operations. In addition to supporting Low Power Ethernet (EEE) on the new generation of enabled MACs, these products can perform EEE on legacy or non-EEE devices by incorporating EEE buffering.

 The devices also integrate an MDI interface termination resistor into the PHY, which simplifies motherboard layout and reduces motherboard cost by reducing the number of components. The new Marvell calibrated resistor solution will meet and exceed the accuracy requirements of the IEEE 802.3 specification for return loss. The device provides equalisation, echo and crosstalk cancellation, data recovery and error correction at Gigabit per second data rates through advanced mixed-signal processing. It achieves robust performance in noisy environments with very low power consumption. 

The 88E1548PA0-BAM2C000 integrates the Advanced Virtual Cable Tester® (VCT™) for fault detection and advanced cable performance monitoring. The Marvell Alaska family of transceiver products provides ideal solutions for the rapid development and deployment of Gigabit standalone and switch systems in the enterprise, embedded, consumer and metro/service provider market segments.

• 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.
