88E1340 Gigabit Ethernet PHY (physical layer) chip

Support 10/100/1000 QSGMII (Quad-Serial Gigabit Media Independent Interface) interface.

Support QSGMII interface for direct connection to MAC chip or SWITCH chip.

The QSGMII interface combines four SGMII interfaces with a rate of 1.25 Gbps into a differential signal with a rate of 5 Gbps.

The QSGMII interface reduces the number of pins connected to the MAC interface and reduces the overall power consumption.

The QSGMII MAC interface can be used as a copper network cable (electrical port) or optical fiber (optical port).

The 88E1340 can also support the SGMII interface on the interface connected to the MAC, which is used for the application of an SGMII interface connected to the electrical interface.

The 88E1340 integrates termination resistors and capacitors for the MDI interface into the PHY. The integration of this resistor simplifies board layout and reduces board cost by reducing the number of external components. The new Marvell calibrated resistor program will meet and exceed Accuracy requirements of the IEEE 80 2.3 return loss specification.

The 88E1340 is fully compliant with the IEEE 802.3 standard. Including PMD, PMA, PCS sublayers. Receivers that perform PAM3, 8B/10B, 4B/5B, MLT-3, NRZI , Manchester encoding/decoding, digital clock recovery, digital adaptive equalizer management functions of the data path, digital filtering of pulse shaping of line transmitters, auto-negotiation, etc.

The 88E1340 device supports Auto-MDI/MDIX at three speeds, making installation more convenient and reducing installation costs.

Support return mode for diagnostics/tests.

in a 15x15mm 196-pin TFBGA package.

88E1340 operating modes:

4 SGMII ports for electrical connections

4 QSGMII ports for electrical connections

4 QSGMII to SGMII ports

4 QSGMII ports for electrical/optical auto media

2 SGMII ports connected to two electrical/optical ports for automatic media

• 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.
