Background technology
Along with the development of space technology, satellite load data amount is increasing, thereby impels the speed of world wireless data sending link also increasingly high, and the data transfer rate of world wireless data link is increased near 1Gbps from 300Mbps before at present.After ground receives data, need the baseband signal storage be got into computer to carry out follow-up data processing.
In the face of the two-forty base band data of nearly 1Gbps, how effectively, reliably it is write computer and become a urgent demand.Computer high-speed data communication technology mainly contains USB, PCI, SATA and PCIE technology at present.The USB2.0 flank speed only reaches 480Mbps, and SATA is used for the data-interface of hard disk at present; And the development of companies such as PCIE technology process Intel, the at present the highest transfer of data (X16) that can support to surpass 10Gbps, PCI reaches as high as 1.8Gbps.
PCI is owing to be parallel data transmission (32 or 64 buses), though its message transmission rate can reach about 2Gbps at present, its development potentiality and scalable space are little.
And the PCIE technology is a Serial Data Transfer Mode, and its 1 the tunnel (X1 pattern) can be transmitted the data of 2Gbps, so its X4; X8, the X16 module provides enough spaces and its nuclear interface standardizing for expanding and upgrading; During customer upgrade, need not do too many design alteration to communication interface.
Simultaneously, the high speed data transfer that 1Gbps is above uses common cable or coaxial cable all can bring higher cost and expense, and common cable can only adopt parallel schema, and coaxial cable needs a pair of at least.And the use Optical Fiber Transmission only needs one, and its Electro Magnetic Compatibility and transmission range all have higher assurance.
As the recipient of base band data, only through 1 road optical fiber with high-speed data acquisition, then through the PCIE interface give computer store will be a kind of very effectively and reliable solution.
