5 Video Data Output Modes
This section describes the video data output modes available on the camera. The video data output
mode will determine the format of the pixel data output from the camera and will affect the camera’s
maximum allowed line rate.
5.1 Overview
The camera can operate in different "video data output modes." The video data output mode will
determine the format of the pixel data output from the camera. The video data output modes
available vary on each camera model as shown in Table 11 on
page 86 .
The main difference between the video data output modes is the amount of pixel data that will be
output on each cycle of the Camera Link pixel clock. In the 2 tap modes, data for 2 pixels will be
output on each cycle. In the four tap modes, data for four pixels will be output on each pixel clock
cycle. And in 8 tap mode, data for 8 pixels will be output on each pixel clock cycle. The selection of
a video data output mode also determines the bit depth of the transmitted pixel data. The video data
output modes are described in detail in Section 5.2.1 on
page 88 through Section 5.2.3 on
page 105 .
In general, you can operate the camera at a higher maximum line rate when you use an output
mode with more taps. This is true because the modes with more taps output a greater amount of
pixel data on each cycle of the pixel clock and therefore require less time to output a given amount
of data.
For more information about how the video data output mode will affect the camera’s maximum
allowed line rate, see Section 4.3 on
page 74 .
On some camera models, the Camera Link pixel clock speed is fixed at 40 Mhz. On other models,
the speed can be set to either 40 or 80 MHz. The available clock speeds on each model are also
shown in Table 11. For more information about setting the Camera Link pixel clock speed, see
Section 2.8.4 on
