Description
Technical field
The utility model relates to technical field of the computer network, is specifically related to a kind of PCIE switching PCI-Express.
Background technology
At present, industry control, the requirement of war products to network interface are higher, and in order to improve the reliability of transmission data, distant in transmission range, when environment is more severe, generally all adopt kilomega network to communicate.General commercial notebook generally only has 100,000,000 nets, and general notebook all has PCIE interface, so we devise this PCIE and turn PCI-Express, can pass through PCIE interface, uses interface chip to realize changing out the function of kilomega network.
The utility model relates to the interface card that a PCIE interface turns gigabit network interface (Gigabit Internet), it is a high reliability, be easy to the network interface card expanded, be applicable to the application scenario needing multiple kilomega network, be equally applicable to the portable computer not having gigabit mouth.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of Based PC IE interface to realize kilomega network function by interface chip, thus enrich computer interface.
The technical scheme that the utility model adopts is:
A kind of PCIE transfers PCI-Express, and described network interface card comprises the PCIE interface, the PCIE that connect successively and turns kilomega network chip, network transformer, kilomega network interface, and be connected to the FLASH storage chip that PCIE turns kilomega network chip, and described network interface card adopts multilayer circuit board.
Described PCIE turns the chip RTL8111DL that kilomega network chip adopts REALTEC company.RTL8111DL is core of the present utility model, and it is responsible for a PCIE protocol conversion and becomes gigabit fidonetFido signal.
Described network transformer adopts the transformation chip H5007 of pulse company.Realize network interface voltage transitions.
Described FLASH storage chip adopts AT93C46.Network/MAC address is write with a brush dipped in Chinese ink by flash chip and is stored.MAC Address is write with a brush dipped in Chinese ink under DOS environment.First enter DOS running environment, obtain MAC Address, MAC Address is preserved into .CFG file, start with USB flash disk under DOS and write with a brush dipped in Chinese ink MAC Address.Restart computer, can observe in the screen lower right corner that the display of gigabit networking icon is normal.Connect gigabit networking to test, normal network interface communication can be carried out.
Described multilayer circuit board adopts 4 layers of pcb board, and wherein internal layer is VDD-to-VSS layer, and other is two-layer is element signal layer.By bus plane and stratum segmentation, set up bus plane+3.3V and+1.0V network, increase wiring completion rate, ensure that the convenience of cabling and decrease number of vias, ensure that Electro Magnetic Compatibility.Digitally, power supply isolate, components' placement has taken into full account size and position, ensure that the device layout of circuit board is reasonable.
GND and GNDP two networks are set up on the stratum of described pcb board, make digitally, isolate power supply, carry out Region Segmentation isolation to the signal on network transformer both sides, reduce signal disturbing and to heavy current circuit overstriking.By isolating transformer, network signal is isolated, realize the object of isolation voltage 2500V.
The beneficial effects of the utility model are: the utility model, it is a high reliability, be easy to the network interface card expanded, be applicable to the application scenario needing multiple kilomega network, be equally applicable to the portable computer not having gigabit mouth, can PCIE interface be passed through, use interface chip to realize changing out the function of kilomega network, working stability, improves the reliability of transmission data.
