Description
Technical field
The present invention relates to electronic engineering field, and in particular to a kind of synchronizing signal backboard.
Background technology
Traditional radar or the communication technology are all to carry out certain coded treatment to reach the effect of certain to radio wave.
Such as radar using coding techniques come improve spatial resolution and enhancing electronic warfare capability, communication system using coding techniques come
Improve the capacity of channel.But as technology develops, it just can not continue to improve radar or communication system by coding techniques
The performance of system.Radar in order to continue to improve its spatial resolution and enhancing electronic warfare capability, it is proposed that utilize multiple transmittings
Propagation path of the radar signal in space is deduced with passage is received, so as to improve resolution ratio.Communication system in order to accommodate at the same time
More communication channels, also require using it is multiple transmitting and receive passage come improve the channel carrying capacity of base station and eliminate multipath
Effect, and the multipath effect building is further cut down.So radar and communication require that system can allow
It is multiple to launch and receive the ability that passage works at the same time.
One of key that multiple transmitting receiving channels work at the same time is exactly to need to several digital analog converters
（DAC）/ analog-digital converter（ADC）Progress operates at the same time.Wherein digital analog converter is responsible for transmitting terminal and analog-digital converter is responsible for connecing
Receiving end.One key request of this operation is exactly multiple digital analog converters or multiple analog-digital converters must operate at it is same
A clock frequency is more likely mutually concerned between channel in the following, otherwise the ability of the multichannel of system cannot not only play on the contrary
Disturb and cause system not run.So people are generally believed using coaxial cable to transmit the synchronous of low frequency on engineering
Number control the digital analog converter either frequency of analog-digital converter clock chip and the number of digital analog converter or analog-digital converter
It is believed that number then being transmitted using optical fiber or coaxial cable.The uniformity of length is to ensure that synchronizing signal can between coaxial cable
A key index of clock chip is reached at the same time.The problem of yet with production technology, the uniformity of coaxial cable can not be very
Ensure well, so can only be different in size to cable to reduce synchronizing signal using low frequency (1 megahertz or less) synchronizing signal
The susceptibility of sample.The problem of so bringing is exactly that synchronous signal frequency is low, and synchronous effect is bad.Also it is exactly excessive cable
Optical fiber be easy to wrong among the process either repaired is installed thus influence the complete machine of radar or communication system installation and
Maintenance.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, present invention aims at a kind of synchronizing signal plate is provided, it is synchronously believed

4th connector module connects, and the 3rd connector module is connected with host computer, the 4th connector module and slave computer
Connection.
As the improvement of above-mentioned technical proposal, first group of connector module uses 64 PCIEx4 interfaces.
As the improvement of above-mentioned technical proposal, the signal wire error in length is no more than 5mil.
As the improvement of above-mentioned technical proposal, the signal wire uses differential signal line.
As the improvement of above-mentioned technical proposal, first group of special purpose interface includes the first special purpose interface, second special connects
Mouth and the 3rd special purpose interface.
As the improvement of above-mentioned technical proposal, second group of special purpose interface includes the first special purpose interface and second and special connects
Mouthful, first special purpose interface is connected with the 3rd connector module, and second special purpose interface is connected with the 4th connector module.
As the improvement of above-mentioned technical proposal, backboard size is 1200mm × 530mm × 2.0mm.
As the improvement of above-mentioned technical proposal, back plate dielectric uses high frequency plate FR4 either Rogers 4350 or 5880.
The beneficial effects of the invention are as follows：A kind of synchronizing signal backboard, passes through all terminals of the first special purpose interface and radio frequency group
The 100 equidistant connection of part connector module, signal wire error in length are no more than 5mil, substantially increase the length of synchronous signal line
Uniformity so that synchronizing signal can walk the frequency of higher, improve synchronous effect, and synchronous signal line is also integrated in backboard and works as
In, time of assembling and maintenance is greatly saved.
