2.3 Camera Link Tap Geometries
All racer Camera Link cameras have a settable Camera Link Tap Geometry parameter. The Camera
Link tap geometry setting determines how pixel data will be transmitted via the Camera Link
interface.
The available Camera Link tap geometries are:
 1X
 1X2
 1X4
 1X8
 1X10
The sections 2.3.3 through 2.3.6 include descriptions of all available tap geometries.
2.3.1 Factors Influencing the Timing of Pixel Data
Transmission
2.3.1.1 Camera Link Pixel Clock
The Camera Link pixel clock is used to time pixel data transmission. The camera transmits data on
each rising edge of the pixel clock as shown, for example, for the 1X2 tap geometry in Fig. 10 on
page 31. The pixel clock frequency depends on the current setting of the camera’s Camera Link
Clock Speed parameter. See Table 14 for the available Camera Link pixel clock speeds and the
related pixel clock (pclk) periods.
2.3.1.2 Delays
In addition to the Camera Link pixel clock, the three delays A, B, and C are involved in timing pixel
data transmission. The delays can be calculated using the formulas 1, 2, and 3 given below. See
also Fig. 10, Fig. 12, Fig. 14, and Fig. 16):
 Delay A takes account, among others, of the time needed for sensor readout and is subject to
the Offset X setting for the image AOI.
 Delay B takes account of the Width setting for the image AOI and of the number of taps used
for pixel data transmission (e.g. two taps in 1X2 tap geometry).
 Delay C takes a minimum (C
min
) of seven pixel clock periods and increases as the line
acquisition rate is decreased. Delay C varies somewhat due to jitter.
