camera link线缆说明线缆、接插件的选用对于系统的最终性能测试非常关键，因此要求较高的系统必须选用可靠的线缆，推荐使用市场标准线缆，尽可能不要自定义线缆。
接插件MDR26采用MDR26接插件，共26个pin脚，

关键术语参考Pixel Depth像素采样深度，一般有8 ， 10 ， 12 ， 14 ， 16几种选择，指代一个像素对应的bit位数；
Pixel Clockcameralink的时钟，时钟应当允许被disable ，时钟支持5-85MHz不同速率；
Taps/ Geometryhttps://www.baslerweb.com/fp-1510660945/media/downloads/documents/framegrabber_designers/AW00099004000_ace_beat_Camera_Link_Info_Frm_Grab_Designers.pdf
参考basler 的手册说明，我们的simulator计划支持下面2种格式，其它的格式在未来支持medium模式时再引入。
1X2-1Y表示在X方向，一次发送2个像素，在Y方向，一次发送一行，按照逐行扫描的顺序向外发送。
1X2-1Y Geometry – 8, 10, or 12 Bit Pixel DepthThe characteristics of the 1X2-1Y tap geometry are:

On each cycle of the Camera Link pixel clock, the data for two pixels are transmitted via the Camera Link interface. This is commonly referred to as a "two tap" Camera Link configuration.
The camera will begin transmitting data from sensor line one. It will transmit the data for the first two pixels in line one on the first Camera Link pixel clock cycle, the next two pixels in line one on the second pixel clock cycle, the next two pixels in line one on the third clock cycle, and so on until the line is complete.
When line one is complete, transmission of line two will begin and will proceed in a similar fashion. Data transmission will continue line-by-line until all of the data for the image have been transmitted.
