1.4. Typical Application
A typical CLT-302 application is shown in Figure 1-4. An LVDS camera is connected to
the CLT-302L using a camera cable that incorporates a 100-pin connector and pin
assignments for use with the CLT-302L and RS-232 camera communication . The CLT-
302L is connected to the frame grabber using a standard Camera Link cable.
The camera in this example is 8-bit, dual-channel, area-scan with a 20MHz pixel clock
and LVDS signaling. The frame enable and line enable timing signals are conventional
active-high. The camera does not generate a data valid signal. Data sampling was found
to be best performed using the falling edge of the camera pixel clock, which is sometimes
the case. In addition, the serial control port on the camera is RS-232. The corresponding
mode switch settings are shown in Figure 1-5. Note that the clock multiplier feature is not
required in this example since the pixel clock is within the 20-85 MHz range required by
Camera Link.
The Camera Link frame grabber is programmed for area-scan, base-configuration, dual-
channel, 8-bit mode. The pixel clock rate is set at 20MHz and video timing is set to match
camera characteristics.
Camera control signal CC1 is routed from the frame grabber, through the CLT-302L, to
the camera for use as an EXSYNC pulse, exposure control, etc.
The serial port in the Camera Link frame grabber is used to control and monitor camera
functions.
