Abstract
The utility model relates to a novel SDI (standard data interface) signal extender, which comprises a BNC (bayonet nut connector) input end and a BNC output end. The novel SDI signal extender also comprises an equalizer, a high-speed transceiver, a jittering removal unit, a high-speed transmission unit and a circuit driver connected sequentially. When the novel SDI signal extender is used, the input SDI signals can be extended to twice of the existing distance through clock recovery. In addition, the novel SDI signal extender has a low cost and can be easily realized.
Description
Technical field
The utility model relates to digital signal transmission field, especially a kind of New type of S DI signal extender.
Background technology
Along with the digitlization process of radio and television is constantly deepened, digital signal has had application more and more widely, and relevant with it product is also more and more, and the quality requirement of product is also more and more higher.Therefore, about the processing of digital signal, the major issue that realization has just become research and development of products.
Sdi signal is a kind of digital video signal of serial, and when frequency was high more, its transmission range was near more.Though long-distance transmissions SDI can realize that the cost height of realizing is not easy to high volume applications by modes such as optical fiber.
The utility model content
At the weak point that exists in the above-mentioned technology, the utility model provides a kind of mode by clock recovery, the sdi signal of input is extended to the New type of S DI signal extender of 2 times far away of existing distances.
For achieving the above object, the utility model provides a kind of New type of S DI signal extender, comprise BNC input, BNC output, also comprise equalizer, high-speed transceiver, go dither unit, high speed transmitting element, line driver, described equalizer, described high-speed transceiver, described dither unit, described high speed transmitting element and the described line driver of going connect successively.
Described BNC input is connected with described equalizer.
Described line driver is connected with described BNC output.
Compared with prior art, the utlity model has following advantage:
A kind of New type of S DI signal extender that the utility model provides can extend to the sdi signal of input 2 times far away of existing distance by the mode of clock recovery.In addition, the utility model cost low, be easy to realize.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
The main element symbol description is as follows:
1, BNC input 2, equalizer 3, high-speed transceiver
4, remove dither unit 5, high speed transmitting element 6, line driver
7, BNC output
Embodiment
In order more clearly to explain the utility model, the utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model provides a kind of New type of S DI signal extender, comprises BNC input 1, BNC output 7, also comprises successively the equalizer 2, the high-speed transceiver 3 that connect, removes dither unit 4, high speed transmitting element 5, line driver 6.BNC input 1 is connected with equalizer 2, and line driver 6 is connected with BNC output 7.
Operation principle:
Import from BNC input 1 through the sdi signal behind the certain distance, after via line equalizer 2 amplifies signal equalization, send into the high-speed transceiver 3 of FPGA, high-speed transceiver 3 is with signal decoding, isolated clock signal is carried out stabilized treatment through going dither unit 4, sends into high speed transmitting element 5 after clock and the data stabilization, and via line driver 6 is delivered to 7 outputs of BNC output again, the signal that comes out from BNC output 7 has possessed standard sdi signal characteristic, can be sent to next stage once more.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
