Video Data Output ModesBasler sprint Color Cameras 1295.2.2 3 Tap Output Modes3 Tap - 10 Bit Output ModeIn 3 tap 10 bit mode, on each pixel clock cycle, the camera transmits data for three pixels at 10 bitdepth, a line valid bit, and a data valid bit.In the 3 tap output modes, the camera uses the output ports on Camera Link Transmitter X and Yto transmit pixel data, a line valid bit, a data valid band, and a pixel clock. The assignment of thebits to the output ports on Camera Link Transmitter X and Y are as shown in Table 16 on page 131and Table 17 on page 132 respectively.The Camera Link clock is used to time the transmission of acquired pixel data. As shown inFigure 19 on page 46, the camera samples and transmits data on each rising edge of the clock. TheCamera Link pixel clock frequency is as stated in Section 2.8.5 on page 38.The line valid bit indicates that a valid line is being transmitted. The data valid bit indicates that validpixel data is being transmitted. Pixel data is only valid when the line valid and data valid bits areboth high.3 Tap - 8 Bit Output ModeOperation in 3 tap 8 bit mode is similar to 3 tap 10 bit mode. In 8 bit mode, however, the two leastsignificant bits output from the camera’s ADCs are dropped and only the 8 most significant bits ofdata per pixel are transmitted.NoteThe video data output mode that you select may affect the camera’s maximumallowed line rate. See Section 4.3 on page 107.The data sequence outlined below, along with Figure 19 on page 46,describes what is happening at the inputs to the Camera Link transmitters inthe camera.
